7 * core.c (core_open): Improve error message for bad file.
8 Pass .reg virtual memory address to fetch_core_registers to help
9 it find the registers in the core-file header.
10 * coredep.c (fetch_core_registers): Take new argument, use it,
11 and pass it to register_addr to locate the block of registers.
13 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
14 Sequent N_FN_SEQ like everybody else's N_FN.
16 * main.c: Circumvent SCO cc bug with #if !!defined(USG).

20 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
22 * doc/refcard.tex (sec "Working Files"): consistent metavars, due
23 to François Pinard (pinard@iro.umontreal.ca)
25 * doc/gdb.texinfo (appendix "Installing GDB"): changes in configure.
27 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
29 Changes from Fred Fish:

40 (echo_command): Use printf_filtered, and force output out.
42 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
44 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
45 * utils.c (_initialize_utils): If !ISATTY, don't paginate.

49 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
51 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
52 (nodes Continuing and Stepping; Memory; Targets) clarifications
55 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
57 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
58 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.

63 generic routines for calling inferior functions.
65 * blockframe.c (inside_main_scope, inside_entry_scope): New.

77 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
79 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
80 This avoids coredumps under `set print object on' in value_headof
81 (called erroneously by value_from_vtable_info) for `p &struct'
82 or `p *struct'. From Peter Schauer.
84 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
86 * Makefile.in: Roll version to 4.1.2.
87 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
88 size from BFD (but, FIXME, we don't yet read external nlists's and
89 convert them to internal nlists's before handling them -- we still
90 assume they have the same size and alignment.) Use SET_NAMESTRING
92 * exec.c (exec_file_command): Move dead coff-encapsulation code
94 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

101 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
103 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
104 * mips-xdep.c (store_inferior_registers): Don't try to
105 write the (pseudo) FP.
106 * mipsread.c (parse_partial_symbols): Improved algorithm for
107 setting pst->texthigh.
109 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
111 * doc/Makefile: make TEXINPUTS include . everywhere
113 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
115 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
116 vestiges of typevectors, which were for symsegs and are no longer
117 used. (From a question by Eliot Dresselhaus
118 <dresselh@RFT30.nas.nasa.gov>).
120 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
122 * dbxread.c, coffread.c: static-ize functions that were
123 gratuitiously external. (From Fred Fish.)
125 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
127 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
128 until it is large enough.
130 * dbxread.c (read_type): Handle error case slightly better.
131 Make complaint message not C++-specific.
133 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
135 * infrun.c (wait_for_inferior): Fix step/next so that you only
136 stop at the beginning of a new line. This fixes various problems
137 with for loops, nested if-else's and switch statements.
139 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
141 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
142 between symtabs and psymtabs become ordinary error()s.
144 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
145 properly, making "end pc" correct in shared lib psymtabs.
146 (From Guy Harris <guy@auspex.com>.)
148 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
150 * dbxread.c: Enable, but soften, const_vol_complaint.
151 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
152 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
153 should be file-scope, not global.
154 (read_struct_type): Remove ancient multiple-inheritance warning.
155 (read_range_type): Check base type, complain & patch if undefined.
156 * stack.c (frame_info): Demangle the function name in `info stack'.
159 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
161 * eval.c (evaluate_subexp_for_address): Don't use
162 TYPE_POINTER_TYPE directly (it might be zero if this type has
163 never had a pointer created before); use lookup_pointer_type.
164 * symtab.c (lookup_method_type): Arguments were swapped in all
165 callers, so fix it here. I'm amazed this worked at all!
167 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
169 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
170 "bss" rather than "data" symbols, but which still conflict.
173 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
174 * core.c (core_files_info): Shorten output.
175 * exec.c (exec_files_info): Ditto.
176 (build_section_table): Ignore zero-length sections.
177 * language.c, printcmd.c: Lint.
178 * language.h (get_frame_language): Declare.
179 * saber.suppress: update.
180 * stack.c (find_relative_frame): Remove complex code that was

184 * utils.c (parse_escape): Avoid \a due to bdead compilers.
185 * value.h: Declare typedef_print.
187 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
190 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
191 (Reported by Mark Peek <mark@imagen.com>.)
193 * solib.c (solib_map_sections): Relocate all sections, even
194 though only the text section's size is tracked. Mark ld_text
195 for eventual elimination as we generalize to N sections.
197 * infrun.c (wait_for_inferior): Don't check if the PC is in a
198 call_dummy if we were stopped by a random signal that is being
199 passed to the program. This produced wierd results when calling
200 functions in the inferior and signals (e.g. SIGALRM) were in use.
202 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
204 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
205 Bugfix from Paul Eggert <eggert@twinsun.com>.
206 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
207 * valprint.c (print_floating): Print 9 digits for IEEE floats.

221 * language.c (set_language_command): Print useful help message,
222 and restore the language string after giving help.
223 * valprint.c (typedef_print): Print typedef in C or M2.
224 * symtab.c (list_symbols): Use it.
225 * main.c (main): Avoid any output before (gdb) prompt when -q.
226 * language.c (set_language_command): Handle errors by restoring
227 the language string to its current state (fix from A. Beers).
228 * doc/gdbint.texinfo: Roll in information from README. Rearrange
229 "how to install" and "how to print the doc" stuff so it drops
231 * configure.in: Rename rtpc CPU to romp to match config.sub.
232 * README, WHATS.NEW, TODO: Update for gdb-4.1.
234 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
236 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
237 autoloading shared libs, copyright etc on GDB startup, clean up $_
238 and $__ index refs, set/show listsize and related updates to list
239 cmd. New host/target configs.
241 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
243 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
244 from main Makefile.in version definition
245 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
247 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
249 * doc/gdb.texinfo: merge new language-switching and lang-specific
252 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
254 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
255 compilers (which may lack stddef.h).
257 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
259 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
260 N_WARNING are the same except for the N_EXT bit, so just use their
261 values alone, rather than OR-ing them with N_EXT.
263 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
265 * mipsread.c (parse_lines): Deal with negative extended line
268 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
269 global symbol conflicts.
271 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
273 * .gdbinit: Move 'set complaints' to top, so it runs even in
274 case we aren't debugging GDB.
275 * language.c (_initialize_language): Fix type check and range
276 check documentation strings.
277 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
278 language.c can use it. (Though language.c should really not be
279 handling warnings/errors the way it does, FIXME.)
280 * symtab.c (lookup_primitive_type): const lint.
282 Bugfix from Peter Schauer:
283 * source.c (lines_to_list): Make signed, to avoid comparison
284 going unsigned and complaining that -3 is too high for 21 lines.
285 * stack.c (lines_to_list): Ditto.
287 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
289 * Makefile.in (HFILES): Add minimon.h.
290 (VERSION): Roll version number to 4.0.95.
291 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
292 New rules for building distributions. Normal distribution
293 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
294 one level up from here; it calls make-proto-gdb.dir to build a
295 directory `proto-gdb' which is an image of the release. The old
296 `gdb.tar.Z' rule still works too.
297 * config.sub, configure: Roll in latest from ..
299 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
301 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
302 new-target, and new-config chapters; fix minor typos; come closer
303 to usual GNU markup conventions for @file @samp @code @var.
305 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
307 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
308 * mipsread.c (parse_partial_symbols): Enter the name of all
309 structs/unions... into the psymtab so we can access them if the
310 symtab is not read in.
311 * mips-tdep.c: Remove some unneeded #includes.
312 * xconfig/dec3100: Add HAVE_STRSTR.
314 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
316 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
317 * c-exp.y, m2-exp.y: Lint.

319 * valprint.c (val_print_fields): Check for stub type.
320 * mipsread.c (_initialize_mipsread): Avoid using
321 builtin_type_void at initialize time.

324 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
326 Merge multiple-language support, and partial Modula-2 support,
327 from Andrew Beers <beers@cs.buffalo.edu>.
329 * i387-tdep.c: New file, consolidates most 80387 support,

423 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
425 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
426 entries are enclosed herein. Not all of these changes
427 have been merged into the master GDB sources -- check the
428 ChangeLog above here for the merge log.
430 Mon Jun 3 17:05:45 EDT 1991
432 m2-exp.y Created. Tested outside of GDB for a few days. Proper
433 operators were added, C specific operators and tokens
434 removed. yylex() revamped to some extent. Still things
435 missing from the grammar, such as sets.
436 Tested for two weeks in GDB v3.5.
438 Tue Jun 11 17:23:48 EDT 1991
440 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
441 so they are built-in. Sort of a hack.
443 Fri Jun 14 12:53:51 EDT 1991
445 m2-exp.y Added range checking for numeric constants. Any numeric
446 constant is assumed to be of builtin type INTEGER unless:
447 (1) it is octal or hexadecimal, in which case it is a
448 CARDINAL; (2) it is too big to fit into an INTEGER, in
449 which case it is a CARDINAL.
450 eval.c Added simple range checking for +, -, and * on integers.
451 Doesn't work very well for *, since 6 * 1,000,000,000 =
452 1,705,032,704, which fails the simple test of result >=
453 first_operand, no matter in what order the operands are.
455 Tue Jun 18 14:11:30 EDT 1991
457 Broke the parser into parts, one containing the C grammar and the other
458 containing code to be shared by all of the grammars.
460 The following files no longer exist:
465 The following files were added:
467 c-exp.y (The C grammar)
468 m2-exp.y (The Modula-2 grammar)
469 parser-code.c (Code that is shared by the above grammar)
473 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
474 now necessary to use the Bison compiler compiler, since it
475 will generate function/variable prefixes other than yy.
477 Tue Jun 18 16:47:49 EDT 1991
479 symtab.[ch] Added the external variable working_lang, than holds the
480 value of the current working language.
481 Added the ennumerated type language_mode, with the values
482 language_auto and language_manual, the former meaning that
483 GDB sets working_lang as needed, and the latter meaning
484 that the value of working_lang is totally under user
486 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
487 REAL, BOOLEAN and CHAR. Also added the type codes
488 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
489 utils.c Added set_language_command and show_language_command to
490 implement the GDB support commands "set language" and
492 expression.h A number of identifiers were added to the type exp_opcode
493 to facilitate Modula-2 builtin functions, integer
494 division, and array indexing.
496 Wed Jun 19 13:25:58 EDT 1991
498 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
499 if the language specified by working_lang requires the use
500 of strict typing of expressions. Eventually, even this
501 will be able to be changed by the user.
502 Added the macro RANGE_CHECK, which evaluates to non-zero
503 if the language specified by working_lang requires the
504 checking of a value against the domain of its type.
505 Eventually, even this will be able to be changed by the
507 language.[ch] Predicates involving types (simple_type, ordered_type,
508 same_type, integral_type, numeric_type, character_type,
509 boolean_type, float_type) are added. These predicates are
510 based on the current value of working_lang, and are handy
513 Wed Jun 19 15:39:34 EDT 1991
515 eval.c Added the function type_array_rank which computes the rank
517 valarith.c Added the funtion value_bool, which when given a integer
518 value.h value (ie. struct value *) as an argument, it returns a
519 boolean value (ie. struct value *) true if that integer
520 is non-zero, and a boolean value false otherwise.
521 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
522 will print out properly.
524 Wed Jun 19 16:36:34 EDT 1991
526 valops.c Added the function value_capitalize, which returns it
527 value.h argument capitalized if its argument is a lowercase
528 letter, or the argument unchanged if its argument is not a
530 valarith.c Added the function range_check_p, which returns non-zero
531 value.h if its value argument is between the integral bounds upper
533 Added the function range_check_enum_p, which makes sure
534 that its value argument is a valid member of the domain of
536 Added the function range_check_range_p, which makes sure
537 its value argument lies between the upper and lower bounds
538 of its type argument, which must be a ranged type.
539 Added the function check_array_index, which range and type
540 checks an index of an array.
541 Added the function value_multi_subscript, which computes
542 array[idx1,idx2...idxN], given a value array and an array
543 of values representing indicies.
544 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
545 unpack_long to work with TYPE_CODE_BOOL and
548 Wed Jun 19 18:04:08 EDT 1991
550 symtab.c Stored pervasive types in a structure and make
551 lookup_pervasive_type() a lookup function that was based
552 on working_lang. If lookup_pervasive_type() returned
553 non-zero, then that value was returned (a fix, since
554 before it simply wouldn't return the pervasive type.)
555 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
556 non-zero if the language specified by working_lang means
557 "conversion" when it says "cast".
558 valops.c Added the function value_real_cast(), which performs a
559 value.h *cast*, not a *conversion*, which is what value_cast()
560 does when it can. In particular,
561 value_cast(<float_type>,4) = 4.0, while
562 value_real_cast(<float_type>,4) = some mess.
563 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
564 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
565 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
566 and MIN on integral types. *NOTE*: These are currently
567 hardcoded to work only if there are 8 bits per storage
569 eval.c Made logical functions call value_bool to return a
570 properly typed boolean value, based on working_lang.
572 Thu Jun 20 11:55:27 EDT 1991
574 valprint.c Types now print out in a Modula-2 fashion. This works for
575 the cases when the type is printed out step-by-step, that
576 is, it doesn't work when the name of a structured type
577 (which includes the keyword "struct", etc.) is simply
579 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
580 since type specifications in C and Modula-2 are very
581 different. The C printing of a type is very recursive,
582 whereas in Modula-2 it is generally very simple. C has
583 type prefixes and suffixes, which have no real analogue in
584 Modula-2. Maybe type_print() should call a language
585 specific type printer. This is also advantageous if we
586 compile GDB to exclude some of the languages. We'll just
587 leave those functions out.
589 Thu Jun 20 16:57:10 EDT 1991
591 dbxread.c When reading the complete symbol table in (via
592 psymtab_to_symtab()), the number and types of function
593 arguments are added to a function type. define_symbol()
594 calls add_param_to_type() to accomplish this.
595 Assumption: when we come across a function definition
596 (N_FUN symbol with an 'f' or 'F' in the name), its
597 arguments will appear before another function definition.
598 When a function is found, a pointer to its type is placed
599 in the global in_function_type. Changes that
600 add_param_to_type() makes are to this global.
601 valprint.c The type of a function now includes (for Modula-2) the
602 types of its parameters.
603 eval.c Type checking and a check for the proper number of
604 arguments is now done for function calls. Not sure of the
605 impact this has on C++ member function yet.
607 Thu Jun 20 19:58:48 EDT 1991
609 valprint.c Rewrote the type printer. Broke it into two language
610 specific parts, adding the functions type_print_m2() and
612 An unfortunate consequence is this: if you debugging a C
613 program in Modula-2 mode (why?), info types does not work
614 well with regular expressions, since the types are printed
615 out in Modula-2 terminology, but stored in C terminology.
616 language.[ch] Added the functions new_type_last(), type_keyword(), and
617 type_sep() to aid in the printing of typedefs.
618 symtab.c Made the printing of typedefs as language independent as
619 possible through calls to new_type_last(), type_keyword(),
622 Fri Jun 21 11:50:26 EDT 1991
624 dbxread.c Check all incoming ennumerated types. If it looks like
625 Modula-2's BOOLEAN type, then change the type_code of the
626 type to TYPE_CODE_BOOL so we can process it as a boolean
628 valprint.c Replaced some of the 0x%x with calls to sprintf and
629 hexformat() in val_print().
630 language.[ch] Added the function hex_to_string(), which converts its
631 integral argument to a hexadecimal number (format is
632 language based) and returns the result as a string.
634 Mon Jun 24 12:25:07 EDT 1991
636 valprint.c Some functions call type_print_1() directly, instead of
637 value.h using type_print(), so they can specify where (column) to
638 print things. Since type_print() takes care of language
639 dependence, that needs to be called first. Added a
640 parameter depth to type_print() (so it is now like
641 type_print_1). Changed type_print to type_print_at, and
642 made type_print a macro that passes a depth argument of
644 symmisc.c Changed all calls to type_print_1 to calls to
646 Makefile.dist Made it possible to build GDB for a specific set of
647 depend languages. Do this by passing a definition for the macro
648 LANGS to make. LANGS should be a string containing a
649 space-separated list of language names (ie. LANGS="c m2").
650 The default is to build all languages. Note that grammar
651 files must follow the naming convention of <lang>-exp.y.
652 gdb.lang This holds the current value of the LANGS macro. It is
653 examined every time make is called, and is updated if
655 eval.c Added #ifdef _LANG_<lang> to these files.
656 expread.c Still need to add them to dbxread.c and coffread.c.
664 Mon Jun 24 16:33:11 EDT 1991
666 language.[ch] Added the functions hexformat_pre() and
667 hex_to_string_pre(), which take a prefix argument to
668 include in the format string. Thus, hexformat_pre("08") will
669 return "0x08x" (if the working language is language_c).
670 Made hexformat() and hex_to_string() calls to the above
671 with "" as the prefix argument.
673 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
674 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
675 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
676 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
677 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
678 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
679 valprint.c, vax-pinsn.c
681 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
682 calls to hexformat() and hex_to_string(). Format strings without
683 the leading "0x" were ignored.
685 depend Updated to take the above into account.
688 Tue Jun 25 15:27:18 EDT 1991
690 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
691 and type_check_t to keep track of the current state of
692 range and type checking.
693 main.c Added the variables range_mode, range_check, type_mode,
694 and type_check to record the current state of range and
695 type checking. Added initialization code to main().
696 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
700 Tue Jun 25 17:57:08 EDT 1991
702 dbxread.c process_one_symbol() updates the variable (enum language)
703 source_lang based on the extension of the filename
704 contained in the N_SO sybmol that started this symtab.
705 When end_symtab() is called, the value of source_lang is
706 put into the language field.
707 stack.c select_frame() sets working_lang (and possibly type_check
708 and range_check) to the language field of the symtab
709 associated with the frame that is selected if working_mode
710 is language_auto. If working_mode is language_manual, a
711 warning is printed and working_lang is not set.
712 language.c Added the function set_type_range(), which sets the value of
713 type_check and range_check (if their modes call for
714 automatic setting) based on the current value of
715 working_lang. A non-zero argument will cause the current
716 settings to be output.
719 Wed Jun 26 14:51:40 EDT 1991
721 eval.c Added range checks on assignment.
722 m2-exp.y Added the grammar for sets to the language. Currently,
723 these do not do anything except print an error message.
725 Wed Jun 26 17:01:04 EDT 1991
727 m2-exp.y Added the ability for parse_number() to parse negative
728 numbers. A global flag is set upon encountering a unary
729 minus. This was done to make, for example, 1 parse as a
730 CARDINAL, and not as an integer, per Wirth's examples in
731 Programming in Modula-2 ed.4.
732 valprint.c Added support for "set radix 2" by then setting
733 output_format to 't'.
734 eval.c Implemented range checking on subrange types. Added calls
735 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
736 Implemented MIN and MAX for ennumerated types. The
737 minimum value of an ennumerated type is defined by Wirth
738 as the first identifier, and the maximum as the last.
739 m2-exp.y Made octal numbers ending with "B" be characters and those
740 ending with "C" be numbers, per Wirth's book. (p. 34)
742 Thu Jun 27 14:11:52 EDT 1991
744 stack.c select_frame() now only sets working_lang, it does not
745 notify the user. If working_mode is language_manual, then
746 a warning is issued once.
747 main.c At the end of each call to execute_command(), working_lang
748 is checked against the local static (enum language)
749 current. If they differ and working_mode is
750 language_auto, the new settings of language, type and
751 range checking are printed out.
752 stack.c Modified frame_info() to include the language of the
753 current frame in the output of "info frame".
754 language.[ch] Added the function language_str() which returns the name
755 of the current language.
757 Fri Jun 28 15:33:14 EDT 1991
759 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
760 the language. INCL and DECL currently cause an error,
761 since sets are not implemented yet. INC and DEC are
762 implemented as PREINCREMENT/PREDECREMENT with one
763 argument, and as ASSIGN_MODIFY with two arguments.
764 eval.c Added type checking to the above cases.
765 value.h Added not_lval_constant to the lval_type ennumerated type.
766 not_lval_constant means that the value is a constant
767 value; that is 3 or 'a' or TRUE, not as in a constant
768 identifier. This is used to help coerce numbers such as 3
769 to either signed or unsigned numbers.
770 valops.c Added the function value_coerce_constants() which coerces
771 constant integers as following: if one is a constant and
772 the other is not, the constant's type is set to the type
773 of the other argument. If both are constants and one is
774 signed, the other is converted to a signed constant.
776 Sat Jun 29 17:26:29 EDT 1991
778 valarith.c Added a better range checker. It now checks range
779 (successfully) on integral operations [+-] (signed and
780 unsigned) for any C sized type. Still does not work well
782 int_in_size() returns an integer that is coerced to fit into
783 specified number of bytes.
785 Mon Jul 1 13:04:14 EDT 1991
787 language.[ch] Added the function binop_result_type(), which returns the
788 builtin (struct type *) type that would be the result of a
789 binop on the two values V1 and V2.
791 Wed Jul 3 19:22:53 EDT 1991
793 source.c Extended source_info() to include the source language in
794 the output from "info source".
796 Fri Jul 5 13:48:52 EDT 1991
798 utils.c Moved the support functions for the GDB set/show commands
799 dealing with language into language.c.
800 language.c Added the function language_info(), which displays info
801 about the current working language, type and range check
802 settings. Called via the GDB command "info language".
803 Added an initialization routine _initialize_language(),
804 that sets defaults for the language, type and range
805 variables and sets up the new GDB commands.
806 main.c Language setup moved to language.c.
809 Mon Jul 8 10:10:22 EDT 1991
811 valarith.c Debugged the range checker for arithmetic. Still does not
812 work for multiplication very well.
814 Mon Jul 8 12:40:37 EDT 1991
816 language.[ch] Added the function value_true() which returns non-zero if
817 its argument represents a boolean true value.
818 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
819 check the truth of an expression.
821 Thu Jul 11 12:51:34 EDT 1991
823 language.[ch] Added the predicate structured_type(), which returns
824 non-zero if the argument is a structured type.
825 Added the predicate pointer_type(), which returns non-zero
826 if the argument is a pointer type.
827 eval.c Added the ability to do addition and substraction on
828 pointers and integers. This case simply bypasses the
831 Thu Jul 11 14:41:42 EDT 1991
834 Added the symbol N_DEFD (0x4a) which is a definition
835 module dependency that is used by the GNU Modula-2
836 compiler and the linker. It is not important to GDB,
837 except that [dbx|coff|mips]read.c should ignore these
840 Fri Jul 12 16:07:00 EDT 1991
842 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
843 0 in val_print(). Also added statements to the else part
844 to coerce type (argument to val_print) to a pointer type
845 if it is an "array of unspecified length".
846 valops.c Added the function value_m2_string(), which returns a
847 (value) value which is a constant string, whose type is
848 (ARRAY [0..n] OF CHAR). The length field of the type
849 structure is set to zero, so it will be interpreted as an
850 "array of unspecified length".
851 stack.c Moved the language/frame mismatch check to
852 main.c:execute_command().
853 main.c The working language is recorded each time
854 execute_command() is executed. If working lang has
855 changed during its execution, then the new
856 language/type/range info is printed out for the user. If
857 the working language does not match the language of the
858 frame, a warning is issued.
860 Sat Jul 13 16:16:39 EDT 1991
862 eval.c Moved all the type-checking stuff for operators to
863 language.[ch] language.c. This is so we can keep language-specific
864 stuff (like for what type operators are defined) in
866 language.[ch] Added the function binop_type_check(), which checks to see
867 if its two (value) arguments are type-compatible with its
868 opcode argument. The opcode should represent an operation
869 involving an operator. Also added the macro function
870 unop_type_check, which calls binop_type_check with a
871 NULL second argument.
872 expprint.c Added Modula-2 operators to the op_print_tab, so info
873 expression.h break works correctly. Also added "op_string", which
874 returns the string corresponding to the (enum exp_opcode)
875 opcode that is its argument.
878 Sat Jul 13 18:26:18 EDT 1991
880 coffread.c Added code to record the type of function arguments with
881 each paricular function. Code is very similar to that
883 dbxread.c Moved add_param_to_type() to symtab.c
884 symtab.[ch] Added function add_param_to_type() from dbxread.c
886 *** NOTE: The above additions have not been tested.
888 Mon Jul 15 12:50:47 EDT 1991
890 langauge.[ch] Added the functions type_error and range_error, which work
891 like error() except if the type/range mode is set to
892 *_mode_warn, then they do not do a return_to_top_level(),
893 but merely print a warning.
894 Also changed [set|show]_[type|range]_command() to support
895 the new "warn" feature.
897 Thu Jul 18 17:50:54 EDT 1991
899 mipsread.c Added code to record the type of function arguments with
900 each particular function. Code is very similar to that
903 *** NOTE: The above additions have not been tested.
905 Fri Jul 19 11:19:10 EDT 1991
907 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
908 UMIN_OF_SIZE, which when given a size of a numeric type,
909 return the maximum and minimum value it can hold. UMAX...
910 and UMIN... return the result for unsigned types.
911 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
912 struct types. They call above macros.
913 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
914 avoid a name conlict with the above.
915 c-exp.y Added range checking on numeric constants in
916 parse_number() for completeness.
917 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
918 return 0 if working_lang is not language_c.
920 Thu Aug 8 14:17:22 EDT 1991
924 breakpoint.c Documentation strings of some commands changed to
925 eliminate the references to the C language where
928 Tue Aug 13 15:48:03 EDT 1991
930 m2-exp.y Added qualified identifiers to the grammar. The semantics
931 are slightly different from those of the GDB operator ::
933 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
934 type_exp, where type_exp is any valid type expression.
936 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
937 printcmd.c Modified ptype_command() so it actually parses the input
938 (necessary for type expressions with scope qualifiers).
939 Added the function ptype_eval() which expects an
940 expression composed of one OP_TYPE element.
941 *.[ch] Replaced all occurences of parse_c_expression with
943 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
945 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
947 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
949 Small fixes from Peter Schauer:
951 * infrun.c (child_attach): Lint.
952 * solib.c (find_solib): Handle shared libs version 2.
954 Small fixes from David Wood:
956 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
960 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
961 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
963 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
964 chars_per_line is at maximum (user typed `set width 0'). Fix
965 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
967 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
969 * coredep.c: include ptrace.h where necessary.
970 * mipsread.c(parse_lines): fix unsigned char problem that was
971 messing up line numbers on SGI's and possibly other MIPS based
973 * infrun.c (child_create_inferior): use better test to check
974 return val from setpgrp().
975 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
976 for sgi/irix support.
978 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
980 * mipsread.c (parse_symbol): Put non-static procedures
983 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
985 Patch together `text_start' and `text_end' for 29K port.
987 * exec.c (exec_command): If NEED_TEXT_START_END, define the
988 variables and set them based on the exec file.
989 * am29k-tdep.c: declare text_start.
990 * valops.c (call_function_by_hand): declare text_end.
992 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
993 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
994 because machines that do this will also have to know to
995 set NEED_TEXT_START_END. Besides, it was a redundant way to
997 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
998 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1001 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)

1006 Pass MUNCH_DEFINE to munch whenever we run it.
1007 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1008 format string; use 0x%x instead.
1009 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1010 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.

1020 Merge target arm case with other "easy" cases. Add target
1021 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1022 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1024 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1025 * munch: Cope with RT/PC putting fns in data segment.
1026 Restore ability to override `nm' by specifying MUNCH_NM.
1027 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1028 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm

1031 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1032 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1033 * tm-29k.h: Update BADMAG (though it should go away).
1034 Allow the register definitions to be overridden in another
1035 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1036 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1037 DUMMY_SAVE_GR96, for handling kernel calling conventions
1038 that use GR64+ rather than GR96+.
1039 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1040 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1041 overrides various things.
1043 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1044 child_attach does, making a clean stop in the newly attached
1046 * remote-eb.c: Lint.
1048 * coffread.c: Make coffread independent of any particular
1049 variant of COFF. Avoid #include-ing any particular one except
1050 internalcoff.h. BFD now passes key values for symbol reading
1051 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1052 and the symbol masks and shifts); use them.
1053 Remove obsolete end_of_text_addr.
1055 * exec.c: Remove unused include files.
1057 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1059 * Makefile.in (documentation targets): Pass $(M4).
1060 Bugfix from eggert@twinsun.com (Paul Eggert).
1062 * stack.c (down_silently_command): Check for stack existence.
1064 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1066 * Makefile.in (VERSION): Update to 4.0.3.
1068 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1070 * core.c (core_file_command): Print frame at coredump with
1071 its level number, by calling print_stack_frame.
1072 * frame.h: Add selected_frame_level, print_stack_frame.
1073 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1074 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1075 Change print_sel_frame and print_selected_frame callers to
1078 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1079 * symfile.c (free_named_symtabs): Ditto.
1080 * main.c (main): wrap_here needs an arg.
1081 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1082 (solib_add): Avoid noise.
1083 (solib_create_inferior_hook): Lint.
1084 (sharedlibrary_command): Move dont_repeat to here.
1085 * utils.c (error): Call wrap_here to force buffered output.
1087 Small patches from Peter Schauer:
1089 * coffread.c (start_symtab): Free any existing line_vector before
1091 (read_coff_symtab): Ditto for type_vector.
1093 * source.c (lines_to_list): New variable, replacing function.
1094 (all uses): Use as variable.
1095 (_initialize_source): Add 'set listsize' and 'show listsize'.
1096 * utils.c (lines_to_list): Remove function.
1097 * stack.c (print_frame_info): Use as variable.
1098 * defs.h (lines_to_list): Remove declaration.
1100 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1102 * breakpoint.c (insert_breakpoints): Restore warning about
1103 the program might be running in another process, but only for
1104 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1105 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1107 * utils.c (error): if error_pre_print is set, print the string
1109 * main.c (main, print_gnu_advertisement, print_gdb_version):
1110 Reformat legalese so it always prints, but acts as an "I'm here"
1111 message while symbols are being read. If any errors occur,
1112 print a few newlines to set off the message and start it at the
1113 left margin. Remove mention of "help" command, and don't yak
1114 about symbol reading.
1115 (catch_errors): Error string is now printed first in case of
1117 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1118 suggest the "help" command.
1120 * Makefile.in (VERSION): Set to 4.0.2.
1122 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1124 * .gdbinit: Remove useless "rr" command. Set complaints
1125 to 1 for people debugging gdb.
1127 * breakpoint.c, remote-vx.c: Reword strings printed by
1128 catch_errors callers.
1130 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1132 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1133 (Fix from kenc@viewlogic.com.)
1135 Fix some infrastructure to be able to cope with host and target
1136 machines with different sized basic types (ints, ptrs, etc).
1137 (Idea from pierre@la.tce.com (Pierre Willard).)
1139 * values.c (value_from_longest): Rename from value_from_long.
1140 Handle pointer types as well as integers, so that targets with
1141 different pointer sizes from the host can be accomodated.
1142 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1143 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1144 uses of value_from_long to value_from_longest.
1145 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1146 the correct pointer type to value_from_long{est}.
1148 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1150 * remote-vx.c: Remove obsolete code for calling functions via
1151 vxworks kludge interface (it referenced value_from_long).
1153 * valops.c (value_string): Find malloc with lookup_misc_func, not
1156 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1158 Make writing to files work properly. (Fixes to BFD are also needed.)
1160 * core.c (core_open): Open file ourselves, read or r/w, depending on
1161 write_files. Use bfd_fdopenr.
1162 * gdbcore.h (write_files): New variable.
1163 * exec.c (write_files): Define variable, add set&show for it.
1164 (exec_file_command): Use write_files to open for read or r/write.
1166 Make shared library reading happen automatically. These changes
1167 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1169 * inferior.h (stop_soon_quietly): Add to exported variables.
1170 * infrun.c (child_create_inferior): call solib hook, if defined.
1171 (child_attach): call solib hook, if defined.
1172 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1173 (find_solib): Use lookup_misc_func rather than hand-rolled.
1174 (symbol_add_stub): New stub for catch_errors.
1175 (solib_add): Avoid output if !from_tty. Catch errors rather
1176 than just calling symbol_file_add and bombing.
1177 (solib_create_inferior_hook): Interface with the target process
1178 to let it read and alloc shared libs, then figure out what it did.
1180 * core.c (validate_files): Fix typo, soften warning.
1181 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1183 * utils.c (fputs_demangled): Avoid duplicate printing if
1184 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1186 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1187 (Fix from pierre@la.tce.com (Pierre Willard).)
1189 * main.c (catch_errors): Change argument to a char * from an int,
1190 since a char * can point to a struct full of glop, but an int
1191 is not guaranteed to be able to hold a pointer.
1192 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1193 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1194 * core.c (core_open, solib_add_stub): Adapt.
1195 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1197 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1199 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1200 by adding .NOEXPORT target.
1202 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1206 * Makefile.in (VERSION): Roll to 4.0.
1207 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1209 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1211 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1214 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1217 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1219 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1220 reflect above name change
1222 * WHATS.NEW: correct pointer to refcard.
1224 * doc/gdb.texinfo: update New Features, Installing
1226 * doc/gdbint.texinfo: add short description of configure +template
1228 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1230 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1232 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1234 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1235 tar file, add dependencies for referenced doc files.
1237 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1239 * coffread.c, symfile.c, stack.c: saberized.
1241 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1243 * doc/refcard.tex: permuted Essential Commands sec
1245 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1247 set/show symbol-reloading
1248 default set complaints 0
1250 RET-repeat disabled after prompted long displays
1251 processID (attach) interpretation of 2nd GDB cmdline arg
1253 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1255 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1256 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1257 breakpoint.c, main.c: lint.
1259 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1261 Install new configuration scheme for GDB and friends.
1263 * config.sub: Translate ordinary names to three-part names.
1264 * configure: Use three-part names internally.
1265 * configure.in: Translate three-part names to filenames.
1267 * README, WHATS.NEW: Update for gdb-4.0.
1268 * Makefile.in: Roll VERSION to 3.99.
1270 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1272 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1273 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1274 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1275 to single structures rather than arrays; when passing
1276 their address, use &. This avoids trouble with bdead compilers.
1277 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1278 instead. This avoids portability headaches.
1279 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1281 * source.c (open_source_file): Avoid ANSI const bdeath by
1282 skipping declaration and then casting result value.
1283 * tm-hp300bsd.h: Clarify comment.
1284 * utils.c (strstr): Result is const char *; ANSI bdeath.
1285 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1286 since system include file defines it differently from "defs.h",
1287 though the two are equivalent for our purposes.
1288 * tconfig/hp300bsd: Add m68k-tdep.o.
1290 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1292 * tconfig/sun*4: Remove warnings about system assembler.
1294 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1296 * mcheck.c: Avoid warning about undeclared abort fn.
1297 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1298 it causes recursive calls to error() when used in cleanups.
1299 To do so requires that we make it a function, so we do.
1300 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1301 * utils.c (do_cleanups): Remove the current cleanup from the
1302 chain *before* calling it, in case error() is called from it.
1303 The result won't be pretty, but won't be an infinite loop either.
1305 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1307 * dbxread.c (read_struct_type): Grok anon structs for C++.
1308 (vb_name, vptr_name): Null terminate these strings.
1310 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1312 Minor bug fixes from BSD Net2 gdb:
1314 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1315 returns 0, there is no previous frame.
1316 * breakpoint.c (commands_command): If !from_tty, don't call
1317 input_from_terminal_p().
1318 * dbxread.c (record_misc_function): Speed up slightly.
1319 (compare_psymbols): Ditto.
1320 * infcmd.c (do_registers_info): Take a second argument to
1321 determine whether to print float registers. "info registers"
1322 does not do so anymore. "info all-registers" does, now.
1323 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1325 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1326 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1330 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1331 executing_breakpoint_commands if we are interrupted by error.
1332 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1333 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1334 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1335 catch_errors() so we can setup the frame regardless of whether
1336 the shared libs work.
1337 * ieee-float.c (double_to_ieee_extended): Get exponent from
1338 right place in little-endian systems. From John Carey.
1340 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1342 * main.c: Remove unused terminating_signals and catch_termination().
1343 (long_options): Terminate with a zero element.
1344 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1345 (gdb_readline): Make call-compatible with readline.
1346 (init_signals): Improve comments re vfork vs. signal.
1348 * utils.c (prompt_for_continue): Use new gdb_readline().
1349 If we prompt for continuation, we don't let CR repeat the previous
1350 command, once we get back to a prompt. It's too easy to keep
1351 hitting CR, expecting "--more--" prompts, and have some long
1352 command start repeating on you.
1354 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1356 * blockframe.c (frameless_look_for_prologue): Speed up by
1357 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1358 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1359 Define two variants, one faster.
1360 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1361 and return zero, rather than giving an error.
1362 (setup_arbitrary_frame): Initialize the PC in the new frame.
1363 (skip_prologue): Add a second arg saying whether we're just
1364 checking for a frameless function or not.
1366 * core.c (core_open, core_close, core_xfer_memory): Move
1367 section table pointers and bfd* into the target_ops.
1368 (core_open): Allow errors in shared lib reading, etc.
1369 (core_files_info): Describe shared library sections.
1371 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1372 exec_files_info, set_section_command): Move section table
1373 pointers and bfd* into the target_ops.
1374 (add_to_section_table): Add BFD to section table.
1376 * target.c (target_xfer_memory, target_info): Pass target to
1377 xfer_memory and target_info functions.
1380 * gdbcore.h: Move struct section_table.
1381 * target.h: New home of struct section_table.
1383 * solib.c (solib_add): New argument is the target_ops whose
1384 section list is to be added to, if any. Reallocate the
1385 sections in that target to add any that come from shared libs.
1386 (throughout) so_sections renamed to sections.
1387 (solib_xfer_memory): Deleted.
1388 * tm-sunos.h (SOLIB_ADD): Add target argument.
1389 (SOLIB_XFER_MEMORY): Delete.
1391 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1392 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1393 from target_ops. It's the same on all targets. Add two section
1394 pointers to target_ops.
1396 * stack.c (find_relative_frame): Dump ancient algorithm for
1397 "down", just use handy "next" pointers.
1398 (frame_command): Don't error if there is no stack; let user
1401 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1402 modifies static state in the parent process; new_tty itself
1403 runs in the child and modifies the child's file descriptors
1404 to match the saved static state.
1405 * infrun.c (child_create_inferior): Call new_tty_prefork,
1408 * infptrace.c (child_xfer_memory): Add ignored target arg.
1409 * remote-eb.c (eb_xfer_inferior_memory): ''
1410 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1411 * remote-vx.c (vx_xfer_memory): ''
1412 * remote.c (remote_xfer_memory): ''. Rename from
1413 remote_xfer_inferior_memory.
1415 * main.c (main): Only try to attach "corefile" argument if
1416 it starts with a digit.
1418 * symfile.c (symbol_reloading): New "set/show" variable.
1419 (symbol_file_add): Shorten message about symbol reading.
1420 (add_symbol_file_command): Merge with add_syms_addr_command,
1421 since this should work on all targets now.
1422 (stop_whining): Default to zero, to shut up complaints
1423 about bad symbol tables on many systems.
1424 (free_named_symtabs): Just exit unless symbol_reloading.
1426 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1427 and add comment explaining shared library screw.
1429 * source.c: #if defined => #ifdef.
1431 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1433 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1435 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1437 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1438 (doc/Makefile knows how to make one for local config)
1440 * Makefile.in: use doc/Makefile for doc targets
1442 * doc/Makefile: GDB documentation now has its own Makefile
1443 doc/refcard.tex: renamed from "gdbrc.tex"
1444 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1445 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1448 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1450 * values.c (baseclass_addr): When reading target memory, use the
1451 length of the basetype, not the upper type. We've only malloc'd
1452 enough space for the basetype, leading to errors in free().
1454 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1455 ends up as a function specially, since we know the actual type of
1456 the pointed-to address. This (somewhat) fixes display of
1457 expressions that include misc_function_vector names. Try `cond 1
1458 !strcmp("a","b")' then `i b'.
1460 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1461 The child can be proceeded from inside wait_for_inferior in
1462 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1463 getting skipped in that case.
1465 * expprint.c (print_subexp): Use filtered output, since the
1466 subroutines we call use it, otherwise the output is horribly
1467 mangled, since output of wrappable stuff comes out late.
1469 * Makefile.in: Bump VERSION to 3.98.1
1471 * infrun.c (child_create_process): Use execlp to find the
1472 shell to exec our target program. This requires some fiddling
1473 with `environ' since there is no execlpe().
1475 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1477 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1478 Minor rearrangement of refcard permits two new make targets--
1479 gdbrc.dvi DVI output for refcard, using CM fonts
1480 gdbrc.ps PostScript refcard, using PS fonts
1482 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1486 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1487 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1489 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1491 * doc/gdb.texinfo: last changes for release.
1492 Minor typo and formatting fixes; incorporated most fixes remaining from
1493 filed mail commenting on earlier drafts.
1495 Added warnings: pipes don't work in run command;
1496 conditions are converse of assertions;
1497 step over fn without debug info goes to next fn;
1498 vars may have "wrong" values near fn entrance, exit
1500 Added example from Kingston on printing repeated nonadjacent values
1502 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1503 shell mode for signals
1505 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1506 doesn't sound so much like its parent "Stopping and Continuing"; also
1507 moved entries on continue to top of section, so they don't get lost.
1509 Improved installation directions in appendix, added manual formatting
1512 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1514 * configure.in: Remove xm.h and tm.h even if we aren't linking
1515 new ones, so "./configure sun4; ./configure none" does the right
1516 thing. Assume that alldeps.mak and depend are already built in
1517 srcdir, and avoid running "make" (particularly "make depend",
1518 which involves "gcc") from inside configure. Build Makefile
1519 directly rather than building Makefile.conf first.
1520 * configure: Regenerate with above changes.
1521 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1522 to 3.98. Revise gdb.tar.Z procedure to produce a file
1523 called gdb-$(VERSION).tar.Z but which unpacks into a
1524 directory called "gdb". Move non-source files out of
1525 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1526 (depend): Don't try to do "gcc expread.y".
1527 (expread.o): Update dependencies by hand.
1529 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1532 Fixed a variety of small typos that prevented info from formatting
1533 cleanly; altered too-long heading for GPL Appendix, as discussed
1534 w/RMS; Changed date on cover to July 91.
1536 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1539 (1) Applied some fixes due to comments from Larry Breed (easier ones
1540 through chapsec 5.2)
1541 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1542 it's broken in latest texinfo
1543 (3) Introduced *some* use of [] for optional arguments, where
1544 explanation is not simpler by listing cmd w arg and cmd w/out arg
1545 separately. Still not using @deffn.
1546 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1547 couple of headings are too long. Need patches to texinfo or revision
1550 * Partial update to README (which still needs work for this
1551 release!): (1) use of configure corrected for new script,
1552 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1554 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1556 * symtab.c (lookup_symbol): Don't complain right off about
1557 no debug symbols; use the misc function vector first.
1558 (list_symbols): Use misc function vector to find symbols
1559 that don't have debug info, and print them.
1560 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1561 PC range doesn't match symtab PC range, as it does on the
1562 MIPS because our symtab reading isn't perfect.
1564 * dbxread.c (dbx_symfile_read): Make warning about
1565 "no debug symbols" slightly nicer.
1567 * source.c (select_source_symtab): If "main" symbol exists,
1568 but decode_line_spec can't find line info, don't just return
1569 a zero; try other source symtabs or give an error.
1571 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1572 their low addresses first, then rip through fixing high addrs.
1574 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1575 <runene@ifi.uio.no>.
1576 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1578 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1580 * Minor, mostly mechanical, cleanup of doc subdir for clean
1581 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1582 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1584 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1586 Mostly MIPS and general symbol-reading fixups.
1588 * doc/gdbint.texinfo: Add documentation on symbol-reading
1591 * mipsread.c: Remove kludges around #include "ecoff.h".
1592 Remove redefinitions of a_magic, etc, no longer used.
1593 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1594 Fix global overview comments to match symfile.c protocol.
1595 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1596 (mipscoff_symfile_read): Eliminate unused code. Avoid
1597 sorting all the symtabs, when all we have read here is psymtabs.
1598 The symtabs are sorted as they are created anyway. Tell
1599 condense_misc_bunches whether we're mainline.
1600 (psymtab_to_symtab_1): Pass filename when recursing, to make
1601 stack trace more informative.
1602 (parse_partial_symbols): Assume cur_hdr as argument.
1603 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1604 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1605 the TYPE_NAME of char *, since that's done in symfile.c.
1606 (free_numargs, parse_symbol, add_symbol, add_block,
1607 shrink_linetable): Declare these fns void.
1608 (upgrade_type): Convert tree of if's to switch. Clean up
1609 bogus "off == 0" handling with a complaint. Avoid setting
1610 field bitpos and bitsize of array with lower and upper bounds.
1611 Check specified bitsize of elements against their actual type's
1612 bitsize, and complain if different. Complain about unknown
1614 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1615 (psymtab_to_symtab_1): Print names of subsidiary files that
1616 are being read in. FIXME, we read far too many files. This code
1617 is not the problem, the problem is in parse_fdr where the psymtabs
1619 (cross_ref): Result should indicate that we used one aux entry
1620 normally, or two if we encountered a "next" entry. This used
1621 to leave the caller pointing at the wrong aux entry.
1622 (add_symbol): If overflowed cur_block, reallocate it larger,
1623 chase all pointers to it, and complain(), rather than clobber memory.
1624 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1625 (new_field): Only allocate one field initially, not two.
1626 Pull ++ out of macro argument. Simplify.
1627 (_initialize_mipsread): Avoid initialization of importd
1628 global_psymbols and static_psymbols.
1630 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1631 to properly set pst->symtab; avoid searching for it.
1632 (symfile_fns): Improve comments, add a FIXME.
1633 * dbxread.c: Update comments to reflect symfile protocol.
1634 (read_ofile_symtab, end_symtab): Return the symtab.
1635 (psymtab_to_symtab_1): Set pst->symtab.
1637 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1638 whether we're mainline.
1640 * symfile.h (sym_fns): Remove unused sym_discard member.
1641 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1643 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1644 the environment variable is not.
1645 * infcmd.c (finish_command): Use filtered printfs.
1646 * cplus-dem.c: Add struct tags to a few unnamed structs.
1647 * valops.c (value_coerce_array): Improve comments.
1648 * valprint.c (type_print_varspec_suffix): Print array size only
1649 if greater than zero.
1650 * m88k-tdep.c: Shift some lines left by one space, that had
1651 apparently been trashed at some point.
1652 * TODO: More things to do, a few got done.
1654 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1656 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1657 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1659 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1660 * expread.y, findvar.c, symmisc.c: Ditto.
1661 * printcmd.c (address_info): Update printed forms of LOC_
1662 symbols. Elim LOC_EXTERNAL.
1663 (print_frame_args): Keep track of param stack offsets before
1664 re-looking up to find the local register param is kept in.
1666 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1667 Further integration of mipsread into gdb. Eliminate unused
1668 routines, duplicate declarations. Handle static symbols in
1669 psymtabs as well as external symbols. When reading symtabs,
1670 insert symbols into the correct block (global, static, or a local
1672 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1674 (mipscoff_symfile_read): Don't call select_source_symtab.
1675 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1676 rather than SYMBOL_VALUE.
1677 (parse_external): Comment clobbering of top_stack.
1678 (parse_partial_symbols): Update comments. Allocate and parse
1679 static symbols as well as external symbols. FIXME, enum values
1680 are not handled in this pass, but should be. Inline new_psymbol.
1681 Use SYMBOL_VALUE_ADDRESS.
1682 (psymtab_to_symtab_1): Read symbols into global static block
1683 by default (until enter some function's local block context).
1684 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1685 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1687 * source.c (select_source_symtab): Select a source symtab
1688 from either the symtabs or, failing that, the psymtabs.
1689 (list_command): Update error message.
1690 (forward_search_command, reverse_search_command): Use getc, not
1691 fgetc, for speed. FIXME, add comment about buffers that die if
1692 overrun by long line.
1694 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1695 by an entire word, which is not portable, if we have a 32-bit
1696 field. (Code in dbxread.c already turns such bitfields, if
1697 aligned, into ordinary ints, but fixing this will help for other
1698 symbol formats and for future changes.)
1699 * core.c (core_open): Handle ANSI const brain death.
1700 * utils.c (vprintf): Fix varargs typo.
1702 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1704 * findvar.c (find_var_value): Handle &function better.
1705 * TODO: Document work needed on &fn and &array.
1706 * printcmd.c (print_address_symbolic): New arg is the prefix
1707 to print if a name is printed.
1708 (print_address_demangle): Honor "set print address" now.
1709 Use new arg above to improve spacing of output.
1710 * valprint.c (val_print): When printing function pointers,
1711 print symbolic form too.
1712 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1714 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1716 * core.c (memory_error): Reword error msg to mislead less.
1718 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1720 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1721 parse_partial_symbols): Use newer BFD internals (external_filehdr
1722 and external_aouthdr), byte-swap the fields that we care about
1723 before using them, and make the file header data local to
1724 read_the_mips_symtab rather than global.
1726 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1728 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1729 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1731 * main.c (command_line_input): Flush stdout and stderr
1732 before every call to readline. This reportedly fixes a bug
1733 that comes up in Sys V running emacs-gdb and/or xxgdb,
1734 when stdin/out are pipes or sockets.
1736 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1738 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1739 Avoid declaring Makefile dependencies, because GNU Make stupidly
1740 tries to update it if we do.
1742 * coffread.c: Revise for minor changes to bfd internal coff
1745 * configure: If -template= is given a relative path, make it
1746 absolute before recurring in subdirectories.
1748 * configure, configure.in, Makefile.in: Install "configure" script
1749 as replacement for config.gdb.
1750 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1751 * README: Update for configure, mostly. FIXME.
1753 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1754 target config files that they are for the host. When the lines
1755 get copied into the Makefile, this makes it more obvious what's
1758 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1760 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1761 tabs, which end up in the disassembler output inadvertently.
1763 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1765 Make it compile cleanly in an ANSI GCC2 environment.
1767 * blockframe.c: <stdio.h>
1768 * cplus-dem.c: free takes a void *, ifdef __STDC__
1769 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1771 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1772 * stddef.h, stdlib.h: Remove these files.
1773 * symtab.c: Avoid declaring qsort, close.
1774 * symfile.c: Avoid declaring close.
1775 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1776 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1778 Assorted other changes.
1779 * dbxread.c: include "libaout.h", not "liba.out.h".
1780 * printcmd.c (print_frame_args): Set recurse properly for
1781 indentation of struct and array parameters.
1782 * valops.c (value_cast): Allow cast to void.
1783 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1784 single_step() in a target-independent fashion.
1785 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1786 set up to be ready to continue. This makes us target independent.
1787 * infptrace.c (child_resume): Remove call to single_step; now
1788 can single step a SPARC target of any kind.
1790 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1792 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1793 docn into separate sections---basically chapters, plus two loose
1794 pieces that can be configured to go in different places. This
1795 allows GNU m4 to preprocess the manual without coredumping.
1797 * Makefile.dist: tell TeX where to find texinfo.
1799 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1801 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1802 the new target "rdl-apps.texinfo" which captures the Makefile
1803 variable that records where to find the Readline libraries.
1805 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1807 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1808 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1809 * defs.h (const, volatile): Only define if not already defined.
1810 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1812 * README: Update for release 3.95.
1813 * config.gdb: Don't create readline dir in subdir builds.
1814 * main.c: Include with "..." form for non-system include files,
1815 so "gcc -MM" for "make depend" works.
1816 Include readline files with "...h" rather than <readline/...h>.
1817 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1819 * coffread.c: Undo minor damage done by Rich Pixley. Use
1820 different internal and external representations of COFF
1821 data structures. Use new BFD routines for swapping them in and
1823 * symfile.c (free_named_symtabs): Avoid freeing file names that
1824 are null or empty. Old i960 tools seem to produce files that
1825 claim to have empty names, causing each successive file read
1826 to blow away the previous one.
1827 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1828 Move deferred_stores to top of file, but don't separate its
1829 #define's from its variable. Add commentary.
1830 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1831 favor of keeping the (working) config.gdb. Move readline
1834 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1836 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1838 * infptrace.c (fetch_registers): no result, since now void.
1839 * tconfig/news: target depends on m68k-tdep too.
1841 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1843 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1846 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1847 applied various small fixes due to or inspired by RMS comments
1849 * doc/gdb.texinfo: finished using all RMS comments, save those for
1850 appendices on readline and cmd history (which are in other source
1853 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1855 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1856 chapter 9; (2) documented 'break' command's menu mode for
1857 overloaded names, in response to hgs problem report C++ p-31
1859 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1861 * doc/gdb.texinfo: (1) better introductory example; (2) more
1862 consistent use of @code, @samp, @file, @kbd throughout; small
1863 cleanups to first three nodes; (3) new "Contributors" node;
1864 (4) Appendix, Renamed Commands; (5) divert specialized startup
1865 instructions to "Targets" chapter for generic manuals, while
1866 leaving them up front for manuals specific to specialized
1867 environments; (6) apply fixes from RMS comments through chapter 4.
1869 * pretex.m4: modify explanatory text slightly (and redefine
1870 "regexp") to keep GNU m4 from complaining. (It still crashes
1871 later, but one step at a time...)
1873 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1875 * readline/readline.c (update_line): Avoid dereferencing a pointer
1876 before comparing it to its bounds. Saber caught this.
1877 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1878 and only set PC if tgetstr returned non-null. Saber caught this.
1880 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1882 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1883 stuff for config manual) here where it counts; updated
1884 to use new subdir structure (gdb/doc/).
1886 * Makefile: generated from above via
1890 * gdbint.texinfo: added instructions on generating gdb.info* files
1891 locally for release. These are ordinary info
1892 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1893 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1894 to generate these, so we distribute them already formatted.
1896 * gdb.texinfo: included full Info node and menu crud (as generated
1897 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1899 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1900 put in comments-for-future gdb.info target (one day makeinfo will
1903 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1905 * gdb.texinfo: Updated to include new or old undocumented
1906 commands, at least the following (perhaps some others I forgot to
1907 record): info f, info float, info path, info program, info s, info
1908 set, info source, info terminal, info types, info user, set/show
1910 Also covered all recent GDB command renames for v4.
1912 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1914 * mipsread.c: Rather than keeping count of how many symtabs
1915 and psymtabs we have, for sorting purposes, count them when
1916 we need to sort. This fixes bug in rereading of symbol tables.
1918 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1920 * infcmd.c: renamed "info path" to "show paths"
1921 * gdbrc.tex: documented above.
1923 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1925 * remote.c: Fix comments.
1926 * utils.c (error): Force out any pending wrap output.
1928 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1930 * Makefile.dist: Roll VERSION to 3.95.
1931 Fix up "saber_gdb" to work again.
1932 * saber.suppress: Update.
1934 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1935 symtab.h, target.c, target.h: Lint.
1936 * core.c: setup and select frame after reading shared libs,
1937 else reading shared libs will clobber them. Lint.
1938 * utils.c (error): Force out any buffered wrap text.
1940 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1942 * remote.c: Remove decls of memory_insert_breakpoint
1943 and memory_remove_breakpoint, no longer used. (Suggestion of
1946 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1947 to make it easier to interface to "configure"'d libraries.
1949 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1951 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1952 aliases for set/show print.
1954 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1956 * coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
1958 * m88k-tdep.c (IEEE_isNAN): New function.
1960 * infrun.c, m88k-tdep.c, m88k-xdep.c: Change
1961 initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
1963 * infrun.c [TDESC]: Add a bunch of crud.
1965 * xm-88k.h [__GNUC__]: Don't define memset.
1967 * m88k-xdep.c: #if 0 out push_breakpoint.
1969 * tm-88k.h: Define GET_SAVED_REGISTER.
1971 * tm-88k.h: Define DGUX.
1973 * m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
1975 * m88k-pinsn.c (sprint_address): Declare at top of file.
1977 * m88k-xdep.c: #if 0 out core_file_command.
1979 * values.c ({unpack_,value_as_}pointer): Just call
1980 {unpack_,value_as_}long (for now anyway).
1982 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
1983 (psr_register): Change return type to dc_word_t.
1985 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
1987 * m88k-tdep.c (get_saved_register): Add lvalp parameter.

2458 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
2460 * target.h: Add to_doc and target_preopen.
2461 target.c: Add target_preopen and target_command.
2463 (add_target): Call add_cmd and mess with targetlist->doc.
2464 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2465 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.
2466 Call target_preopen from open routine.
2468 * main.c: Rename editing_info to show_commands.
2469 (_initialize_main): Rename "info editing" to "show commands".
2471 * source.c: Rename directories_info to show_directories.
2472 (_initialize_values): Rename "info directories" to "show directories".
2474 * values.c: Rename convenience_info to show_convenience.
2475 (_initialize_values): Rename "info convenience" to "show convenience".
2477 * copying.awk (_initialize_copying): Rename "info copying" to
2478 "show copying" and "info warranty" to "show warranty".
2479 Rename {copying,warranty}_info to show_{copying,warranty}.
2481 * symfile.c: Rename add_syms_command to add_symbol_file_command.
2482 (_initialize_symfile, add_syms_addr_command):
2483 Rename add-syms to add-symbol-file.
2485 Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
2487 * symfile.h (free_named_symtabs): Rename from free_named_symtab.
2488 * symfile.c (clear_symtab_users_once, cashier_psymtab,
2489 free_named_symtabs): Move these routines from symmisc.c.
2490 * symmisc.c (same): same.
2491 (free_symtab): Make non-static.
2492 * symtab.h (free_symtab): Declare as exported void fn now.
2493 * dbxread.c (end_symtab, end_psymtab): Change comments.
2494 (initialize_dbxread): Call dbx_new_init() in case the first
2495 command is add-symbols.
2496 * target.c (dummy_target): Permit add_syms_addr_command.
2498 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2500 Permit symbols to be superseded when new symbol files have
2501 been read in, particularly for VxWorks.
2503 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2504 to the main file, as well as to include files. Also, put global
2505 functions into the global psymtab, to make "i fun" work.
2506 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2507 new psymtab for it has been read.
2508 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2509 a file, once a new symtab has been read for it.
2510 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2511 looks harder to determine the top-level block before it's been
2512 queued to the psymtab list.
2514 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2515 If we have wiped out any old symbol tables, clean up at end of
2517 (symbol_file_command): Don't reference symfile_fns if it's zero.
2519 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2520 defines for the blocks of a blockvector that contain global and
2521 file-static symbols and the first of the smaller scope contours.
2522 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2523 decode_line_1, make_symbol_completion_list): Use the above.
2524 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2525 * dbxread.c (end_symtab): Ditto.
2526 * expread.y (block): Ditto.
2527 * mipsread.c (throughout): Ditto.
2528 * symmisc.c (free_named_symtabs): Ditto.
2530 * symtab.c (list_symbols): Process the first symbol of the
2531 static psymbols list.
2532 (types_info): Restore this function from its untimely #if 0.
2533 It's not perfect, but it is better than nothing.
2534 (_initialize_symtab): Restore "info types".
2536 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2538 * m68k-stub.c: Remote stub for 680x0's, created from
2539 rem-m68k.shar (which is removed).
2540 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2541 Remove RCS log stuff now that we use CVS and it blows our diffs.
2543 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2545 * symmisc.c (free_named_symtab): Make it work, in its current
2546 kludgy fashion. Change result to indicate if we blew away bkpts.
2547 * dbxread.c (end_symtab): Accumulate result from
2548 free_named_symtab and print warning if we blew user's state.
2549 * symfile.h: free_named_symtab now returns an int.
2551 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2553 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2554 is the first symbol read, even if not mainline.
2555 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2556 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2557 (set_section_command): New command ("section xxx yyy" -- should
2558 be renamed to "set section xxx yyy" FIXME) which sets the
2559 base address of a section of the exec file, overriding the
2560 virtual address that BFD reports.
2562 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2564 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2565 load symbols at any address while examining an exec file.
2567 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2569 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2570 for printing the float info is host-dependent, not
2571 target-dependent. FIXME.
2572 * i386-pinsn.c: Move #includes to top, remove useless ones.
2573 * i386-tdep.c: Don't bother including <.../reg.h> since we
2574 don't use it (and it doesn't exist on host systems).
2576 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2577 Convert negative numbers properly.
2578 (ieee_test): Make numbers really random; fix format arg.
2580 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2581 * core.c (core_detach): Unpush core_ops, which might not be on
2582 top. We used to just pop the top, which broke things. Don't
2583 need dont_repeat() any more.
2584 (core_file_command): Psst! Don't repeat it.
2585 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2586 * expprint.c (print_subexp): Avoid switch fallthru on
2587 BINOP_ASSIGN_MODIFY, so we can print += and such.
2588 * frame.h: Fix typo.
2589 * inflow.c (kill_command): After killing inferior, print our
2590 current frame in the core file, if we have one.
2591 (generic_mourn_inferior): When inferior dies, either select
2592 the current frame (in the new target, e.g. core file), or
2593 set both the current and selected frames to NULL.
2595 Changes from Peter Schauer.
2597 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2599 * Make all file names fit in 14 characters (sigh and damn!):
2600 mv hp300hpux-xdep.c hp300ux-xdep.c
2601 mv symmetry-xdep.c symm-xdep.c
2602 mv symmetry-tdep.c symm-tdep.c
2603 mv convex-opcode.h convx-opcode.h
2604 mv tm-vxworks960.h tm-vx960.h
2605 mv tm-vxworks68.h tm-vx68.h
2606 mv Makefile.srcdir Makefile.sdir
2607 mv gdb-int.texinfo gdbint.texinfo
2608 mv remote-sa.m68k.shar rem-m68k.shar
2609 mv remote-multi.shar rem-multi.shar
2610 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2611 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2612 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2615 * command.c (user_info_1, user_info): New command for listing
2616 the user-defined commands.
2618 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2620 * dbxread.c (really_free_pendings): Clear file_symbols
2621 and global_symbols after freeing them; otherwise, running
2622 this function twice (if it appears twice on the cleanup
2623 chain), we try to free things twice.
2625 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2626 based on text_addr (the address of text in core), not on addr (the
2627 offset between text in the .o file and in core). This change
2628 is from Peter Schauer.
2630 * main.c: Define ALL_CLEANUPS as a cast of zero.
2631 (return_to_top_level): Use it.
2632 (main): Do all cleanups after each command run as part
2633 of the gdb startup sequence. Also do all cleanups before
2634 entering the command loop, and every time we exit the command
2635 loop and reenter. Before, the cleanups from the startup sequence
2636 were being left undone until the first error!
2637 (command_loop): Rename do_nothing cleanup to command_loop_marker
2638 so we can see it easily when examining the cleanup chain.
2639 (init_signals): Add another do_nothing for signal handling.
2640 (quit_command): Only try to kill target if it has execution.
2641 Problems in the target stack got us into a state where
2642 inferior_pid was nonzero but none of the targets had execution.
2643 In this state you couldn't exit gdb.
2645 * dbxread.c: Two changes from Peter Schauer.
2646 (echo_command): Fflush output after an echo command.
2647 (show_history): Pass all args to cmd_show_list.
2649 * utils.c (init_malloc): Call mtrace to turn on tracing
2650 if the environment variable MALLOC_TRACE is set to a file name.
2651 * mtrace.c: Add source file which provides a log of every malloc,
2652 free, and realloc to a trace file.
2653 * mtrace.awk: Add source file which analyzes the trace file.
2654 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2655 (VERSION): Roll to 3.94.3.
2657 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2658 (check_duplicates): Don't bother with watchpoints.
2659 (set_raw_breakpoint): Comment about danger of this routine.
2660 (watch_command): Parse and eval all args before calling
2663 * solib.c (find_solib): Avoid error in referencing memory to
2664 see if any more shared libraries have been added. This is
2665 particularly useful if the target has terminated. Bug reported
2668 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2669 in bringing up 3.94.2 on the Sun-3.
2671 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2672 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2673 expression (in scope) before reenabling watchpoint.
2674 * signame.c (init_sigs): Add missing declaration of i, fix
2675 sys_siglist declaration.
2676 * source.c (list_command): Fixed range computation to use
2678 * stack.c (backtrace_command): Do not allow command if target has
2679 no stack, print informative error message.
2680 * target.c (target_command): Do not write into command line
2681 because this fails if the target command is used in a user defined
2682 command. [This change was enhanced by gnu to support any-
2683 unique-prefix matching on target names.]
2684 * valops.c (value_struct_elt): Avoid infinite loop on an
2685 erroneous attempt to print the member of function (try p main.p).
2687 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2689 * expread.y (name_no_typename): Avoid reduce/reduce errors
2690 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2691 Since the GDB parser really doesn't use name_no_typename in a
2692 name-only context, the parser can't tell the diff between
2693 names and numbers here. Avoid allowing a name_no_typename
2694 to be a NAME_OR_*INT to resolve the conflict.
2696 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2698 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2700 * valprint.c (val_print_fields): bitfield printing didn't handle
2701 byte order. Indirect through a few more fns to cope.
2703 * values.c (modify_field): also cope with byte order.
2705 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2707 Cleanup for release 3.94.2:
2709 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2710 include files. Roll version to 3.94.2.
2712 * coffread.c (init_stringtab): Read length into unsigned char
2713 array before swapping; don't assume 32-bit longs.
2715 * target.c (target_info): Don't bother with get_sym_file, just use
2716 the symfile global variable.
2717 * symtab.h, symfile.c (get_sym_file): Delete it.
2719 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2720 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2721 (read_type): Replace one more error() with complain().
2723 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2725 * i960-tdep.c: Fix copyright attribution.
2727 * config.gdb: Quote all backquotes in doublequotes. You can
2728 quote me on that. BSD 4.4 shell found this one.
2730 * infptrace.c (throughout): The third argument to ptrace is an
2733 * infrun.c (wait_for_inferior): When program has terminated, we
2734 have to call target_terminal_ours before we pop that target off
2735 the stack (e.g. before a call to target_kill or
2736 target_mourn_inferior). This fixes problem where a program
2737 terminates, then GDB stops for (tty output) and you have to type
2738 "fg" to the shell to resume it. FIXME: This code for what to
2739 do after termination really should be in normal_stop instead.
2741 * gdbcore.h (read_memory_check): Change declaration; it changed
2744 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2745 4.4 prereleases, this avoids a bug in their sgtty compatability
2747 * remote.c: Use terminal.h rather than hand-rolling the same.
2749 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2750 * utils.c (strsave, strstr): Fix arg types.
2751 * valprint.c (val_print): lint
2753 MIPS symbol table support from Per Bothner:
2755 * symfile.c (symtab_fns): Remove initializer table that needs to
2756 be hacked for each new symbol file format supported.
2757 (add_symtab_fns): New function, chains symbol table
2758 handlers into the global list.
2759 (symfile_init): Search this list.
2760 * symfile.h: Add next pointer, declare add_symtab_fns.
2761 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2762 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2764 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2765 symbol *). Thus, we no longer need the hack to trash
2766 pst->filename. Good, since that hack confused code in symfile.c!
2768 (reorder_symtabs, destroy_all_symtabs): Removed static
2769 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2770 Instead, the latter now uses a temporary array (stack-allocated
2771 from an obstack, and then freed).
2773 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2774 haven't been set in the outermost stBlock of a procedure. This was
2775 a problem with f77 binaries on Ultrix 4.?.
2777 (new_symtab, new_symbol, new_type): Continue changing code to use
2778 obstacks more and otherwise conform to dbxread internal style.
2779 Made the free_code of symtabs be free_linetable (as in dbxread)
2780 instead of free_contents. This implies memory leaks when reading
2781 a new symbol table, until the conversion is finished. Did change
2782 (struct symbol) and (struct type) to be allocated on the
2783 symbol_obstack. Blocks and blockvectors are among the things
2786 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2787 tested much, but it solved one problem (reported by Meissner), and
2788 cleans up some other things. The problem happened when an
2789 included file contains actual code (functions) and not just
2790 definitions. The mips coff is a little inconvenient there, since
2791 it may cause a procedure to be mapped to the wrong psymtab.
2793 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2794 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2795 this will need work for the new core paradigm.
2797 Opcode patches from the net:
2799 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2800 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2801 missing altogether - they are added here. From Bruce Bauman.
2802 * mips-opcode.h: The low mask for C0 instructions was too small.
2803 From Garrett Lau. I modified the fix to check the entire 32-bit
2806 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2809 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2811 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2813 * dbxread.c (read_type): Pointer subtraction (value_sub in
2814 valarith.c) sometimes failed because the types of the
2815 pointers being subtracted were not identical.
2816 These differed because dbxread.c was allocating pointer types
2817 using dbx_alloc_type+smash_to_pointer_type instead of
2818 lookup_pointer_type. I failed to find a justification for the
2819 former, so I changed it to use the latter. Similarly, I
2820 replaced smash_to_function_type by lookup_function_type,
2821 and smash_to_reference_type by lookup_reference_type.
2823 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2824 _initialize_mipsread): corresponding changes.
2826 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2828 * source.c (mod_path): Do tilde_expand on each component of the path,
2829 rather than on the (list of) paths as a whole.
2830 (print_source_lines): Set first_line_listed in addition to
2831 current_source_symtab and current_source_line. If the source was
2832 not findable, after a "dir" command to fix the problem,
2833 a "list" would get the wrong lines.
2835 While I was there... (gnu):
2837 * dbxread.c (read_type): Change error to complaint.
2839 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2841 First attempt at detailed understanding of symbol table memory alloc.
2843 * dbxread.c (dbx_symfile_read): Free our string table if we
2844 aren't the mainline. Free the "info" struct since we're done with
2846 (init_psymbol_list): Free any previously allocated psymbol lists.
2847 (): FIXME: Should realloc-down the psymbol lists when done reading
2848 the main symbol file?
2850 * symmisc.c (free_symtab): Free fullname field too.
2852 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2853 (REGISTER_ADDR): Make result type unsigned int.
2855 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2856 define REGEX must also define REGEX1 (its dependency).
2858 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2860 * tconfig/i960: No longer works, points you at vxworks960 or
2863 * xgdb.c, XGDB-README: Remove file. Users can get the much
2865 * Makefile.dist: Remove all trace of xgdb.
2867 * breakpoint.c (breakpoint_1): Pass demangle arg to
2868 print_address_symbolic.
2869 (clear_breakpoints): Remove unused function.
2870 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2871 (breakpoint_re_set): Use catch_errors to do them all anyway.
2873 * gdb-int.texinfo (Host versus Target): Add section on what is
2874 a "host" feature versus what is a "target" feature.
2876 * infcmd.c (path_command, path_info): Handle the PATH variable
2877 (object search path) as conveniently as the source search path.
2878 * environ.c (set_in_environ): Set some vars in GDB's environment,
2879 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2880 * source.c (mod_path): New function, from guts of
2881 directory_command, modifies a path. Used by path_command.
2882 (directory_command): Call it.
2883 * defs.h (strsave): Declare.
2885 * utils.c (sevenbit_strings): Add new printing option.
2886 (printchar): Use it.
2887 (strsave): Provide this handy helper routine.
2888 (set_width_command): Rename set_screen_width_command.
2889 (_initialize_utils): "set screen-width" => "set width";
2890 "set screen-height" => "set height"; add sevenbit-strings.
2892 * infcmd.c (do_registers_info): Print floating point registers
2893 in raw hex as well as float format, regardless of whether it is
2894 a "virtual" convertible register.
2895 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2896 regs as a double, just in case it's being used that way.
2897 * values.c (unpack_long): Comment on array/function coercion.
2898 (unpack_double): Argument is in target byte order now. For
2899 integer arguments, just call unpack_long and float the result.
2900 * m68k-tdep.c: include defs.h for "const" handling.
2901 * remote-nindy.c: Use ieee-float stuff.
2902 (nindy_fetch_registers): Unpack double regs to host double, then
2904 (nindy_store_registers): Pack extendeds to host double, flip
2905 around by misusing unpack_double, send as target double.
2907 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2908 zero, as when stopped at the first instruction of a process.
2910 * blockframe.c: Fix filename in comment (param.h => tm.h).
2911 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2912 * tm-68k.h: Fix typos.
2914 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2916 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2918 * coredep.c (fetch_core_registers): Pass end-address of register
2919 section to register_addr as expected. Don't call supply_register
2920 if we'd just pass it garbage.
2922 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2924 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2926 * target.c (push_target, target_info): Cast enums to int for < or
2929 * stack.c (print_frame_info): Identify source file & line
2930 even if we can't print it.
2932 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2934 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2936 Clean up IEEE floating point support.
2938 * ieee-float.h: New file.

2948 * m68k-tdep.c: Define ext_format_68881.
2949 * sparc-tdep.c: Define ext_format_sparc, though unused.
2950 * Makefile.dist (HFILES): Add ieee-float.h.
2951 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2954 Obsolete the "coffstrip" program in favor of using BFD's strip.
2956 * nindy-share/coffstrip.c: Remove file.
2957 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2958 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2959 * tconfig/nindy960: Remove reference to coffstrip.o.
2961 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2963 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2965 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2966 * dbxread.c: Remove static symfile_bfd.
2967 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2969 * inftarg.c (child_detach): Pop the child_ops vector if the
2970 detach is successful.
2971 * remote-nindy.c (nindy_create_inferior): Don't push a new
2972 nindy_ops since nindy uses the same one for execution and memory
2974 * core.c (core_ops): Use child_attach and child_create_inferior
2975 rather than default attach and create_inferior functions.
2977 Handle floating point registers in core files.
2979 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2980 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2981 This version untested since BFD doesn't yet support sun3 core
2983 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2984 conventions. Fix comments and style. This version has not
2985 been compiled yet, since we have no HP inhouse.
2986 * core.c (get_core_registers): Look for two sections, ".reg"
2987 and ".reg2", and pass both to fetch_core_registers sequentially.
2989 Revise directory path yet again.
2991 * source.c (forget_cached_source_info): Not static any more.
2992 (init_source_path): New default source path is "$cdir:$cwd".
2993 (dir_command): Handle variable arguments ($cdir, $cwd).
2994 (source_info): Print "Compilation directory" rather than
2995 "Originally compiled in" to remind people of $cdir.
2996 (openp): If the path contains $cwd, use current directory.
2997 (open_source_file): If compilation directory is known, replace
2998 first $cdir in path with the compilation directory.
2999 (print_source_lines): Even if we can't print the lines, set the
3000 current symtab and line for future commands like "info source" or
3001 "breakpoint". Also, error message now contains the file name,
3002 line number, and file access error message.
3003 (_initialize_source): Fix help text to describe changes.
3004 * main.c (cd_command): Forget cached source info when we chdir.
3005 * utils.c (strstr): Add simple implementation.
3007 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3009 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3010 Byte-swap COFF symbol tables if necessary when reading them in.
3011 Use complain() to replace error message in one spot. Needs
3012 corresponding change in bfd/coff-code.h to make some symbol
3013 swapping routines non-static.
3015 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3017 Merge changes from Eirik Fuller, for UTek.

3025 declarations of errno.
3027 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3029 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3030 <rpc/rpc.h> and <rpc/types.h>.
3032 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3034 * i960-tdep.c (examine_prologue): Add new argument limit,
3035 which stops the scan at the end of the prologue, or at the PC.
3036 This fixes a problem where it walks down into the code for the
3037 user's statements if that code looks like function prologues.
3038 Mark Fox and I have been bouncing this code back and forth, making
3039 small changes to it. Callers changed to match.
3041 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3043 Cleanup for gdb-3.94 release final:
3045 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3046 the .c files from vx-share and nindy-share, from the various
3047 macros, since they are not found via ALLDEPFILES.
3048 (SFILES): Add tm-i960.h.
3049 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3050 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3052 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3053 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.

3057 * am29k-tdep.c: Add contribution line.
3058 (examine_prologue): Cache information about function prologues in
3059 the misc-function-vector to avoid lots of references over the
3060 serial line while examining instructions.
3062 * core.c (core_close): New function made from cleanup_core.
3064 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3065 remote-vx.c, remote.c, target.c, target.h,
3066 Update target_ops vector to add attach, close, and load entries.
3067 Use add_syms_addr_command, not add_file_addr_command, for
3068 add_file. Break out close routine from existing code.
3070 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3071 they are in an obstack.
3072 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3074 (define_symbol): Add symbol type parameter; change callers;
3075 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3076 it to influence the symbol class on the i960.
3077 (define_symbol): Swap LOC_CONST's into target byte order.
3079 * exec.c (exec_close): New function.
3080 (exec_file_command): Call it.
3082 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3083 Fix byte order of frame pointer.
3084 (read_var_value): Result of 0 if var's value can't be found,
3085 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3086 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3087 (locate_var_value): Use read_var_value and use its lazy address
3088 as the location of the var's value. Lint.
3090 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3093 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3094 obsolete Intel versions in favor of vxgdb versions.
3095 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3096 code dealing with byte order of values, which Intel did in host byte
3097 order rather than gdb-4's target byte order.
3098 (i960_frame_chain_valid): Move to nindy-tdep.c.
3099 (examine_prologue, skip_prologue, frame_find_saved_regs,
3100 frame_args_address, leafproc_return, saved_pc_after_call,
3101 pop_frame): Add vxgdb versions from Mark Fox.
3102 (examine_prologue, frame_struct_result_address): Add code
3103 to deal with the saved value of G13 (struct return address
3105 (frame_args_address): Modify Mark's version to prefer the
3106 saved value over the current value in the topmost frame.
3107 Cache result in the frame info to avoid performance hair in
3109 (print_fault): Add gdb960 code for printing faults.
3110 (_initialize_i960): Actually call check_host.
3112 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3113 add stub routines. FIXME, these currently just return zero!
3115 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3116 (attach_command): Call target_attach, not target_open, now.
3118 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3119 (child_attach): Rename from child_open.
3120 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3121 don't confuse it with a zero step_resume_break_address.
3123 * inftarg.c (child_detach): Eliminate inferior_pid test.
3124 (child_files_info): Clean up message a bit.
3125 (child_ops): Use child_attach, not child_open, to attach.
3127 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3128 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3129 findvar.c to here, since it depends on the contents of the
3130 shadow_contents of breakpoints, but keep if #if 0 since it is
3133 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3136 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3137 (ptype_command, display_command): Eliminate have_inferior_p and
3138 have_core_file_p in favor of target_has_stack or
3139 target_has_execution.
3140 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3141 code for actually finding the values of arguments, though we still
3142 keep track of the maximum stack offset for use in printing unnamed
3143 arguments. Handle missing FRAME_ARGS_ADDRESS.
3145 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3146 (struct nindy_regs): Define registers passed to/from nindy.
3147 (nindy_fetch_registers, nindy_store-registers): Translate between
3148 nindy and GDB formats for the registers.
3149 (dcache_init): Statically allocate the cache, since it was being
3150 allocated by a malloc that was never freed anyway.
3151 (nindy_create_inferior): Error, not core dump, if no exec file.
3152 (nindy_before_main_loop): Use target_load, not target_add_file.
3154 * remote-vx.c (net_load): Specify large timeout for load
3155 requests. Allow user to break out with INTERRUPT.
3156 (net_break): Remove useless code, clean up. Change callers.
3157 (parse-args, skip_white_space, find_white_space): Clean up arg
3158 parsing to cope with quoted strings.
3159 (net_wait, net_quit): Never call error, just return status.
3160 (vx_read_register, vx_write_register): Cleanup status checking.
3161 #ifdef the code based on which CPU we are using (960 or 68k),
3162 FIXME, this should be completely general but it isn't yet.
3163 (vx_xfer_memory, vx_resume): Cleanup status checking.
3164 (vx_run_files_info): Improve message.
3165 (vx_load_command): Renamed from vx_add_file_command. Allow load
3167 (net_ptrace): Remove unused routine.
3168 (vx_wait): Adopt code from vxgdb960 to cope with broken
3169 connections to target machine and prompt to disconnect. Remove
3170 debug printouts. Map some EVENT_'s to SIGnals.
3171 (add_symbol_stub, vx_open): Print names of object files we found,
3172 and "ok" if we read their symbols OK. Clarify output in general.
3173 (vx_attach, vx_detach, vx_kill): Add these commands.
3174 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3175 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3176 "info files" output, and create_inferior, since we already have
3179 * stack.c (frame_info): Replace Frame_unknown with 0.
3180 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3181 (return_command): Pop until the PC matches as well as the FP,
3182 so it works even if the FP is shared with another function,
3183 as in "frameless" or "leaf" procedures.
3185 * symfile.c (load_command): renamed from add_file_target_command.
3186 (add_syms_addr_command): renamed from add_file_addr_command.
3187 (add_syms_command): Stub to call target_add_syms.
3188 (_initialize_symfile): Change command names and descriptions,
3189 add-file => add-syms, and load from alias to its own command.
3191 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3192 maybe_kill_then_create_inferior): Default for attempts to start
3193 a process, if one is already running, is to ask about killing
3194 it and retry if yes.
3195 (upstack_create_inferior): #if-0 it, strata obsolete it.
3196 (push_target, unpush_target, pop_target): to_close() a target
3197 before unstacking it.
3198 (target_info): Renamed from target_files_info.
3199 (_initialize_targets): Rename "i files" as "i target", accessible
3202 * target.h: Improve comments about the target_ vectored routines.
3204 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3205 Convert commenting style to standard GNU style.
3206 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3207 (SKIP_PROLOGUE): No longer a no-op.
3208 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3209 (*_REGNUM): Sort register numbers.
3210 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3211 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3212 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3213 are now 10 byte extendeds, not 8 byte doubles.
3214 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3215 for nindy versus vxworks targets. FIXME, this should possibly go
3216 in the target vector.
3217 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3218 frame_saved_regs and arg pointer with each frame.
3219 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3220 (FRAME_ARGS_ADDRESS): Use cached result.
3221 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3222 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3223 (PRINT_RAMDON_SIGNAL): Call print_fault.
3224 (POP_FRAME): Now works.
3226 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3227 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3228 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3229 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3232 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3233 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3235 * valarith.c (value_subscripted_rvalue): Avoid handling
3236 floats and doubles specially; it gave alignment errors. Lint.
3238 * valops.c (value_of_variable, value_of_this): Error if unknown
3241 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3242 to avoid alignment problems.
3243 (value_print): Handle unknown value address.
3244 (cplus_val_print): Two args are ignored; remove them. Change caller.
3245 (val_print): Use unpack_long rather than pointer-deref.
3248 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3249 to avoid alignment problems.
3250 (value_being_returned): Error if return value unknown.
3251 (set_return_value): Add bogosity warning, FIXME. *
3253 * TODO: A woman's work is never done.
3255 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3256 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3257 Add ieee-float.o to OBS.
3258 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3259 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3260 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3262 Changes to generalize the VxWorks RPC protocol slightly, to handle
3263 i960 as well as 68000.
3265 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3266 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3267 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3268 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3269 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3270 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3271 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3272 so they will move in target byte order rather than network
3273 byte order (happens to be the same).
3275 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3277 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3279 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3282 Add contribution lines to various files, showing where they
3285 * breakpoint.c (break_insn, check_break_insn_size,
3286 read_memory_nobpt): Remove to mem-break.c.
3288 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3291 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3292 entry has bad register number. This change is not
3293 tested in this release, FIXME.
3295 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3298 * value.h: Force value's contents field to be aligned to hold
3299 at least a double or a long long (if supported). This avoids
3300 doing bcopy's in and out of the contents field.
3302 (step_1): Avoid coredump under obscure circumstances when we
3305 * symtab.h (misc_info): Add field to misc function vector for
3306 any kind of cached information the target code desires. AMD
3307 29000 uses this to avoid repeating examine_function_prologue's.
3309 * coffread.c: Lint. Remove static symfile, read_section_header.
3310 core.c (have_core_file_p): Lint: remove.
3311 expprint.c (print_subexp): Lint.
3312 infptrace.c, valops.c, valprint.c: lint.
3314 Roll in changes from vxgdb-5.0.1:
3316 * symtab.h: Comment byte order of each address class. Add
3317 LOC_LOCAL_ARG for frame-relative args (960).
3318 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3319 symtab.c, symmisc.c: ditto.
3321 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3323 * remote.c (remote_resume): Error if resume with a signal.
3325 * symfile.c (prim_record_misc_function): Clear misc_info.
3326 (fill_in_vptr_fieldno): Check stub type of arg.
3328 * valops.c (value_cast): Avoid looking up names of types whose
3329 name we don't know, to prevent coredump. Sun CC produces typedef
3330 rtx and the name of *rtx is zero...
3332 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3334 Roll in changes from final AMD 29000 port (Tiemann).
3336 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3337 for ../include/a.out.encap.h. This might not work now that BFD
3338 is separately compiled. Instead, BFD support for encap will have
3339 to translate machine type 29k into the right COFF_MAGIC.
3341 * infcmd.c: Remove references to inferior_pid that aren't used
3342 in actual ptrace calls; use target_has_execution, etc.
3343 (have_inferior_p): Remove function.
3344 (program_info): Print target info rather than "process number";
3345 avoid gratuitous messages unless from_tty.
3346 (run_stack_dummy, finish_command): Set proceed_to_finish.
3347 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3348 main.c: Lint. Lose have_inferior_p().
3349 inferior.h (have_inferior_p): Remove, lint.
3350 (proceed_to_finish): Add flag to ask that all regs be saved
3351 by normal_stop, for the few commands that need it, speeding up
3352 serial I/O. Add comments to stop_registers.
3354 * remote-eb.c: Remove newline from breakpoint message we grep
3355 for. Never time out when running the user program.
3359 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3361 Roll in changes from vxgdb-5.0.1:
3363 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3364 symbol in its raw form, we are processing an unlinked ".o" file.
3365 See if the target environment has assigned it an address, using
3366 target_lookup_symbol (VxWorks does), and enter it into the symtab
3369 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3370 68k versions for a simpler version that assumes zero FP at bottom.
3371 Fixes bug of truncated stack reports.
3373 * target.h (target_lookup_symbol): Define this routine's args
3374 and result, finally.
3376 * target.c (nosymbol): Default routine for target_lookup_symbol.
3377 (target_default): Default lookup_symbol and call_function too.
3378 (files_info): Only print has_all_memory warning if a non-dummy
3381 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3382 vx_convert_from_virtual): If target does not have floating point,
3383 zero register "values", and avoid doing cross-net conversions.
3384 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3385 (vx_open): Rearrange code that attaches to target and reads
3386 symbols for all loaded modules, to work if some of the modules
3387 are not accessible. Add symbol_stub() and add_symbol_stub()
3388 as callbacks from catch_errors(). Allow connect attempt to be
3389 interrupted painlessly with ^C (FIXME, there are still some bugs
3390 if the interrupt happens during symbol reading.). Print
3391 final message with puts_filtered, since symbol messages are
3396 * main.c (catch_errors): Only print errstring if non-null.
3397 (command_loop): Avoid an ioctl per command to test ISATTY.
3399 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3400 (vx_xfer_memory): Return correct result!
3401 (vx_files_info): Indicate whether target has float or not.
3402 (vx_lookup_symbol): Complain, not error, if target gone.
3403 (vx_open): Print "Connected" msg before disabling immediate-quit.
3404 [FIXME: lookup_symbol and vx_open changes need testing.]
3406 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3407 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3408 contributor lines and update copyrights to 1991.
3410 Changes from an attempted H-PUX host port:
3412 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3413 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3414 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3415 * remote-vx.c: include <sys/time.h> for HPUX.
3416 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3417 "core_file_command" routine to BFD regime. May not work yet.
3419 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3421 * xgdb.c: Replace X10 version with some VJ version.
3422 (FIXME: Its copyright assignment is not on record.)
3423 * xgdb.c: Update include files to X11R4 (Xaw crud).
3424 (xgdb_display_source, create_text_widget): fix call to
3425 get_filename_and_charpos. Rewack source window stuff for X11R4
3426 (gleaned from include files, and "nm's" of binary libraries, since
3427 I had no doc available).
3428 (append_selection, append_selection_word): Disable with FIXME
3429 since R4 changed interface here.
3430 (create_buttons): Add back the old set of buttons.
3431 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3433 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3434 Roll VERSION to 3.94 (not yet final though).
3436 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3438 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3439 obstack_int_grow, obstack_int_grow_fast): Eliminate
3440 cast on left of assignment, which gives MIPS cc fits and is
3443 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3444 F_ALIAS. Use printf, not fprintf, when not passing a file
3446 (compare_opcodes): Check that identical instructions have
3447 identical opcodes, complain otherwise.
3449 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3450 was reported by Roland McGrath.
3451 (unimp): Only match if exactly zero instruction. (Roland)
3452 (branches and traps): Generate all variations of these
3453 instructions with macros, based on a single call that defines
3454 each condition name and its binary representation.
3455 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3457 * valprint.c (val_print_fields): Take, and use, format parameter.
3458 This means that "p/x struct" again prints the elements in the
3459 desired format. Changed callers.
3461 * stack.c (frame_info): Use filtered output, and indicate wrap
3462 points. Remove kludgy formatting designed to avoid line wrap.
3464 * utils.c (wrap_here): If the line is already full (because
3465 we had printed a long indent or long wrapped string), do an
3466 immediate newline-and-indent.
3468 * m68k-pinsn.c (print_insn_arg): Bugfix from
3469 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3470 instruction is incorrectly disassembled as bkpt #8.
3472 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3473 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3474 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3475 and then will dump core (sometimes). I traced it back to an
3476 uninitialized symfile_name in psymtab_to_symtab.
3477 (const_vol_complaint): Add quotes to message.
3478 (define_symbol): Only believe line number if gcc_compiled.
3479 Avoid allocating symbol if we will not return it.
3481 Add target strata support so that newly established targets go
3482 into their right place in the target stack (e.g. a new exec file
3483 doesn't wipe out the ability to access the running process).
3485 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3486 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3487 and initialize it properly in all the targets.
3489 * target.h: Document strata. Change return type of push_target.
3491 * target.c (nomemory): new function for dummy memory access.
3492 (tcomplain): Rename complain, now also used in symfile.c.
3493 (push_target): Push targets within strata. New return value shows
3494 whether new target is on top of stack or not. Always keep dummy
3496 (target_files_info): Ignore dummy target.
3498 * core.c (core_open): Warn user, and skip accessing file, if the
3499 core target is not the topmost target in the stack.
3500 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3503 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3504 target_ops, it doesn't belong there since we have no regs there.
3505 Change name of target from machine => memory to clarify.
3507 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3509 * Freeze version 3.93 for release.
3511 * Makefile.dist: Handle vx-share and nindy-share subdirs
3512 properly when building gdb.tar.Z.
3514 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3515 printed in various places, so I could change just one copy.
3517 * dbxread.c, coffread.c: Change references to bfd->iostream
3518 to cast to FILE *, now that BFD avoids needing types defined
3519 in other header files.
3521 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3523 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3524 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3525 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3526 (actually gcc -Wall).
3528 * dbxread.c: Remove first_global_sym, last_global_sym, since
3529 they are never referenced.
3531 * defs.h (baud_rate): Declare.
3532 main.c: Define it, and add the -b option to set it.
3534 * gdb-int.texinfo: Add text on how to define a new host or target
3535 architecture, prompted by Per Bothner's questions about MIPS
3538 * gdb.texinfo: Document "complaints". Change doc of -q since
3539 gdb no longer prints the copyright and blurb if you specify a file
3540 name to be debugged (just like Emacs). Add doc for Nindy-specific
3541 command line flags for specifying target serial port and such.
3542 Update copyright to 1991.
3544 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3545 has taken over for us the job of ripping up executable files. The
3546 crud caused Per Bothner's port to not compile.
3548 * infrun.c (normal_stop): Avoid printing "Program exited
3549 normally" if we are in batch mode. This allows a GDB which
3550 executes a program on a target system, to behave like a Unix
3551 command (input from stdin, output to stdout, no extraneous
3554 * main.c (main): Allow additional machine-dependent command line
3555 options to be specified with the ADDITIONAL_OPTIONS,
3556 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3557 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3558 processing to occur just before the main loop with
3559 BEFORE_MAIN_LOOP_HOOK.
3560 (main): If a "core file" argument is specified, and it is not a
3561 core file, try it as a process ID to attach.
3562 (symbol_completion_function): Attempt to cope with
3563 "show screen-" TAB, not very successfully. This needs more work,
3565 (batch_file): New function, returns whether we are reading
3566 commands from an interactive tty on stdin, or from somewhere else.
3567 Called by normal_stop since it doesn't get from_tty passed down
3568 to it like many commands do.
3570 * remote-nindy.c: Handle command line options for nindy
3572 (nindy_before_main_loop): Prompt user for tty name if they
3573 don't specify it before getting to the interactive command loop.
3575 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3576 and -r command line options. Also add hook before main loop
3577 to make it easy to specify a tty.
3579 * TODO: More things to do, one done.
3581 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3583 * dbxread.c: Make complaint() calls pass pointer, not struct.
3584 Add complaints about badly formatted C++ type information
3585 (const/volatile indicator, and parse errors resulting in
3586 error_type). Fix C++ virtual member fn comment.
3587 (read_struct_type): Avoid bumping pointer if we got a parse
3588 error; this prevents our walking beyond the end of a string.
3589 Terminate loop on null char as well as semicolon.
3590 (process_one_symbol): Fix the LBRAC fix so that it uses the
3591 last previous SLINE, FUN, or SO record's PC address. C++ debug
3592 symbols did not have SLINE records in a useful order compared
3593 to the LBRAC records.
3594 (define_symbol): Handle "catch" records.
3596 * symtab.c (check_stub_type): Added new complain
3597 `stub_noname_complain' and added a consistency check to
3598 keep the debugger from crashing when finishing from an
3599 exception frame. A real fix will be needed later.
3601 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3603 * infcmd.c (attach_command): Make global.
3605 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3606 but make them easy to comment out. Perhaps later they should
3607 be enabled by what CPU you configure for? FIXME.
3608 (VERSION): Roll to 3.93.
3609 (pinsn.o): Remove rule for obsolete file.
3610 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3612 Run down a problem that manifested by printing the wrong function
3613 name in stack traces of read_ofile_symtab. Turned out that the
3614 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3615 the LBRAC symbol with an address in the *data* segment, which
3616 blew our binary search through the blocks.
3618 * dbxread.c: Use the complain() facility consistently to bitch
3619 about problems in the symbol file we are reading.
3620 (finish_block): Add code to check the nesting of the blocks;
3621 complain and Procrust them to fit if wrong.
3622 (make_blockvector): Check the order of the blocks, complain
3623 [but don't cope] if wrong.
3624 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3625 symbols to be sure their PC value is greater than the last SLINE
3626 (line number) symbol we've seen, complaining and adopting the
3627 SLINE PC value if wrong.
3629 * symfile.h (struct complaint, complaint_root, complain,
3630 clear_complaints): Add.
3631 * symfile.c (complain, complaint_root, clear_complaints): Add
3632 facility to deal with non-fatal complaints and to regularize their
3634 (symbol_file_add): Clear complaint counters to allow new complaints.
3635 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3637 * dbxread.c (dbx_symfile_read): Remember the address and size
3638 of the string table for the main symbol file, so we won't read it
3640 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3641 to avoid reading the string table yet again. Lint.
3642 (throughout): Improve filtered output, including word wrap.
3643 (read_range_type): Improve Bothner's fix to handle other types too.
3645 * utils.c: Improve line wrap implementation. Handle unlimited
3646 width by making chars_per_line unsigned.
3647 (puts_filtered): New, easy, function.
3649 * defs.h (puts_filtered): add.
3651 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3652 call the identical sort_symtab_syms() in symfile.c instead.
3654 * expread.y: Suggest the `file' command rather than `symbol-file'.
3656 * command.h (enum var_types): Add zinteger for seroable
3658 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3659 nested if's into a switch.
3661 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3662 we did not stop because of a breakpoint (it must have been for
3663 some other reason, like a "stepi"), so don't print anything.
3665 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3666 doesn't include <sys/types.h>, old SunOS's require it for
3669 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3671 A test port of gdb-3.92.6 to the Sony NEWS.
3674 Don't normally link in remote- or vx stuff.
3675 Some of it doesn't compile, and it wastes space for 99% of the users.
3676 Remove reference to no-longer-used HAVE_VPRINTF.
3677 Fixed BFD_DEP typo to BFD_DIR.
3679 Fix cast in arg to bfd_h_getlong.
3680 Make char *prefix be const.
3681 Fix how certain range types are mapped into builtin unsigned int types.
3683 Remove 2 #includes. They cause errors (on Sony, at least),
3684 and aren't needed (they wern't in earlier versions).
3686 print_address_symbolic should never demangle labels
3687 (since it prints *assembler-level* labels).
3689 [This was superseded by the change to printcmd below.]
3692 Add some "volatile" return types to avoid warnings.
3693 If MISSING_VPRINTF add vprintf function and not just macro
3694 (since vprintf is used in printcmd.c).
3696 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3697 (The latter isn't grokked by some PCC-based compilers.)
3699 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3701 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3702 * nindy-share/coffstrip.c
3703 Added some forward declarations (otherwise, gcc complains
3704 about implicit extern redefined as static).
3706 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3708 Changes inspired by Per Bothner:
3709 * printcmd.c (print_address_symbolic): Take additional parameter
3710 specifying whether to demangle.
3711 (print_address): Pass in asm_demangle to control demangling.
3712 (print_address_demangle): New fn, takes explicit arg to control
3714 * utils.c: Add new vars demangle and asm_demangle, and let them
3716 (fputs_demangled): If !demangle, just print the argument.
3717 (fprint_symbol): If !demangle, just print raw symbol.
3718 * valprint.c (val_print): Call print_address_demangle rather than
3719 print_address, to cause demangling to depend on the global
3720 rather than assembler-level demangling setting.
3721 * WHATS.NEW, gdb.texinfo: Document.
3723 * main.c (show_command): Show all settings if no arg.
3724 (initialize_main): Make "info set" the same as naked "show".
3725 * command.c (cmd_show_list): Handle prefix commands in the
3726 list, and print the name of the setting as well as its English
3727 description and value.
3729 Allow gdb functions to specify where a line should wrap if it
3730 exceeds the size of a terminal line. Use it to make the output
3732 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3733 of the right size when screen width changes.
3734 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3735 (wrap_here): New fn, indicates a point in the output where we
3736 should wrap the line rather than just letting it overflow at a
3738 (fputs_filtered): Implement wrapping.
3739 (n_spaces): New fn, returns a pointer to N spaces.
3740 (print_spaces_filtered): Use n_spaces.
3741 * defs.h (n_spaces): Declare.
3742 * stack.c (print_frame_info): Wrap with 4-space indent after
3743 fn name and before filename and line number.
3744 * printcmd.c (print_frame_args): Wrap with 4-space indent
3745 before each argument name is printed.
3746 * valprint.c (value_print): Wrap with no indentation before
3748 (val_print_fields): Wrap with indentation relative to nesting
3749 level before each field name.
3750 (val_print): Wrap with nesting indentation before array elements.
3751 * command.c (do_setshow_command): Avoid extra newlines,
3752 wrap with 4-space indent around values printed, end with period.
3753 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3755 * breakpoint.c (breakpoint_1): Implement addressprint for
3756 "info breakpoints" display. Change file name and line number
3757 format to " at file:nnn" rather than " (file line nnn)".
3758 * gdb.texinfo: Document.
3761 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3763 Frozen for gdb-3.92.6 release.
3765 README, WHATS.NEW: Update for 3.92.6 release.
3767 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3768 coffread.o from configs since it is now built by default.
3769 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3770 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3771 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3772 from configs since it is now built by default.
3774 Makefile.dist: Update for release 3.92.6. Handle files that
3775 have been moved to ../include, ../getopt, or ../bfd. Add
3776 saber.suppress and tests directory. Add config.status to
3777 the release (it will say "none").
3779 coredep.c: Minor formatting fixes.
3781 These changes were made in early December but only checked in now:
3782 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3783 nindy-share/nindy.c: lint
3784 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3785 register values coming back from the target; we store values
3786 in target byte order everywhere.
3788 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3790 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3792 * valprint.c (cplus_val_print, val_print_fields): New functions,
3793 which print C++ objects. They conspire to avoid printing a
3794 virtual base class more than once, following all the twists and
3795 turns of C++ virtual base rules.
3796 (val_print): Call the above rather than do it by hand.
3798 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3799 symbol file, not for added files like shared libs. This really
3800 needs to be generalized to a timestamp per file.
3802 * core.c (cleanup_core): Avoid coredump if no core file.
3804 * config.gdb: Accept -host or -target in place of +host or
3807 * coffread.c (find_linenos): Avoid desupported BFD interface
3808 to line numbers. We still read them manually rather than using
3809 BFD's "generic" features.
3811 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3813 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3815 * Makefile.dist: Eliminate use of $< in explicit targets.
3817 * readline/Makefile: Use $< rather than $*.c, which does not
3818 include the VPATH in GNU Make.
3820 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3821 copies of tconfig/i960, added for global configuration
3822 compatability. All i960 versions can read both coff and b.out.
3824 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3825 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3828 * TODO: Think of more things to do.
3830 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3832 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3833 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3834 64-bit float conversion.
3836 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3837 equivalent to sun?os4 so global config works.
3839 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3841 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3843 * main.c: Only declare linesize once; declare pagesize not at
3844 all, since it is never used.
3845 (main): Clear newly allocated line before it is used.
3847 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3849 Further stabilization for the Intel 960.
3851 * Makefile.dist: Parameterize the location of the "include"
3852 and "bfd" directories, as well as "getopt". Add symfile.c.
3853 Link in both dbxread and coffread. Fix up "make depend" to
3854 rewack the locations of include, bfd, and getopt in its output.
3856 * README: Document moving include files, improve some of
3859 * coffread.c: Move common code out to symfile.c. Change
3860 symbol_file_command style interface to use new *_symfile_init
3861 and *_symfile_read interface under BFD. Use BFD internal
3862 info to locate line table, symbols, etc.
3864 * core.c (core_fetch_registers): Rename to get_core_registers
3865 to avoid confusion with fetch_core_registers.
3866 (register_addr): Move to coredep.c, which is already machine
3867 dependent. This leaves core.c pretty clean of dependencies.
3869 * coredep.c (register_addr): Accept this routine from core.c.
3871 * dbxread.c: Move common code (with coffread.c, etc) into new
3872 symfile.c. Each psymtab now contains a pointer to the
3873 format-dependent function that knows how to read it in. Make
3875 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3876 (process_one_symbol): Add code to complain about a "compiler bug
3877 we muzzle here", if we actually see it.
3879 * eval.c (evaluate_subexp): Insert missing "break" statements
3880 in code that determines whether a variable is an lvalue in
3881 memory, register, or whatever. I detected this via a compiler
3882 bug in which it *almost* mashed out the whole switch statement.
3884 * gdb-int.texinfo: Add minor sections on configuring gdb for
3885 release, and about the README file.
3887 * infcmd.c (registers_info): Fix formatting somewhat. Still
3888 not as pretty as before, but it handles byte swapping.
3890 * remote-nindy.c: If data cache routines are interrupted while
3891 waiting for the remote end, be sure that any uninitialized cache
3892 blocks are on the free list, not on the valid list!
3894 * symfile.h: Flesh out this header file with all the various
3895 routines and variables that have been merged in from dbxread.c
3896 coffread.c, and symtab.c to symfile.c.
3898 * symfile.c: New file, containing code common to dbxread.c,
3899 coffread.c, and some code from symtab.c. All generic code for
3900 reading symbol files should be in here now.
3901 (unrecord_misc_function): Remove unused function.
3903 * symtab.h: Remove file-reading things to symfile.h.
3905 * symtab.c: Remove file-reading things to symfile.c.
3907 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3908 to decode i960 fault types.
3910 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3911 target.c: Change type of the "resume" function from int to void,
3912 since its result was never used.
3914 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3916 * main.c: Replace "stupid" with "caution"; you now "set caution
3919 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3921 * infcmd.c (do_registers_info): Call val_print to deal with the
3922 byte order of the registers being printed. FIXME, this makes
3923 the formatting of the output uglier.
3925 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3926 defined, call it for signals the debugger doesn't itself use.
3927 The i960 uses this for more detailed fault information.
3929 * remote.c (remote_open): If arg is null, print help rather than
3932 * sparc-xdep.c (register_valid): Avoid declaring size, since
3933 various modules will think of various sizes depending on the
3934 architecture of their tm-file. FIXME, we need protection against
3935 actually entering one of those modules, which would clobber
3936 storage if not for the target architecture compiled into gdb.
3938 * stack.c (up_command, down_command): Always print the frame
3940 (up_silently_command, down_silently_command): New commands
3943 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3945 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3946 more parameters than it used to.
3948 * findvar.c (registers): Increase slop to 256 bytes, which should
3949 protect us against even most RISC machines with large register
3951 (locate_var_value): Move declaration inside related ifdef.
3953 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3954 throughout, to avoid throwing away buffered input from the board.
3955 (nindy_wait): Supply_register takes addr_of_value, not value.
3956 (i960_print_fault): Renamed from i80960_fault.
3957 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3958 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3960 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3961 we can set the PC in the call to proceed(). Unpush nindy_ops
3962 before pushing it on top, to avoid message to user. Eliminate
3963 commentary from Unix machines that just misleads here.
3964 (reset_command): Fix error message to suggest target command.
3966 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3968 Release 3.92.5 as frozen.
3970 Stabilize the merged release...with help from lint, Saber C,
3973 Everywhere: Add include files needed to declare return types
3974 of functions called.
3976 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3978 * breakpoint.h: Add undeclared breakpoint functions, and some
3979 functions for display handling since I couldn't think of a better
3982 * breakpoint.c (insert_breakpoints): Make code for disabling
3983 shared library bkpts more likely to work. It's used when we
3984 rerun a program and stop before the shared library has been
3986 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3987 cast from pointer, so it squeezes through catch_errors.
3988 (bpstat_stop_status): Fix logic broken some time ago. We now
3989 always create a bpstat if the stop address matches a breakpoint,
3990 even if we don't stop there -- just like the old code used to do
3991 before I got my fingers into it (sigh).
3992 (breakpoint_1): Print "ignore count" after "stop only if"
3993 condition, since that's how it actually works.
3994 (mention): Handle watchpoints as well as breakpoints.
3995 (watch_command): use set_raw_breakpoint and mention to do most
3996 of the work (and initialize all the fields!). Only pass one
3997 arg to parse_c_expression, since that's all it takes.
3999 * command.c (not_just_help_class_command): Rename arg to args
4000 since we ignore "unused argument" warnings on vars named "args".
4001 inflow.c (child_terminal_info): ditto.
4002 infptrace.c (kill_inferior): ditto
4003 main.c (catch_errors, version_info, quit_command, pwd_command,
4004 source_command, dump_me_command, editing_info,
4005 set_history_size_command, set_history, show_history,
4007 stack.c (locals_info): ditto
4008 target.c (target_files_info): ditto
4009 valprint.c (set_input_radix, set_output_radix): ditto
4011 * core.c: Remove old variables for handling core and exec file
4012 sections (data_start, data_end, stack_start, stack_end,
4013 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4014 text_end, exec_data_start, exec_data_end, text_offset,
4015 exec_data_offset, data_offset, stack_offset). They're
4016 superseded the more general build_section_table and
4018 (get_exec_file): Mention the `file' command.
4019 (read_memory_check): Rename to memory_error, and only call it
4020 in the case of an actual error.
4021 (read_memory, write_memory): call memory_error.
4022 (core_fetch_registers): Register section name is ".reg".
4024 coredep.c: Remove a bunch of crud now that all this file does
4025 is pull the registers out of a core file.
4026 (fetch_core_registers): Rewrite to actually work, I hope.
4028 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4029 Replace index() with strchr(). Remove all the pre-BFD macro
4030 definitions for accessing the symbol file.
4031 (struct dbx_symfile_info): Encapsulate the information that
4032 dbx_symfile_init needs to pass to dbx_symfile_read in this
4035 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4036 dbx_symfile_discard): Rearrange symbol file reading to divide
4037 the format-specific part from the format-independent part,
4038 leaving the format-independent part such as file name expansion
4039 and opening in symtab.c. This replaces
4040 partial_symbol_file_open and partial_symbol_file_read.
4041 Symbol_file_read, add_file, add_file_target_command,
4042 add_file_addr_command move to symtab.c. Pass an explicit
4043 "mainline" flag for when reading the main symbol table, rather
4044 than relying on the offset address to be zero or nonzero.
4046 (dbx_symfile_read): Don't allow void *'s to be printed as
4048 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4049 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4050 macro" debug version really work.
4051 (read_dbx_symtab): Remove unref'd parameter inclink.
4052 Avoid swapping N_SLINE symbols, for speed.
4053 Merge N_TEXT!N_EXT case with the other external symbol
4054 definitions' case. Add comments.
4055 (start_psymtab): Allocate the symfile name in the psymtab on
4056 the psymbol_obstack, rather than using the caller's storage.
4057 (end_psymtab): Only allocate a dependencies list if there are
4059 (psymtab_to_symtab_2): Use BFD when reopening file to read
4060 its symbols for real.
4061 (read_struct_type): Add FIXME comments where it needs work
4063 (read_huge_number): Add FIXME about overflows.
4064 (read_range_type): Add FIXME about comparing a long to 1<<32.
4066 * coffread.c: Minor changes to move things closer to the new
4067 regime with symtab.c and dbxread.c Major work is still needed
4070 * exec.c (exec_file_command): Remove old variables (see core.c
4072 (xfer_memory): If memory transfer is right at the end of a
4073 section, don't lose.
4075 * findvar.c (get_saved_register): If value is in a real
4076 register, LVAL is lval_register, not lval_memory.
4078 frame.h: Declare print_sel_frame and record_selected_frame.
4080 gdb-int.texinfo: New file, for GDB internals documentation.
4081 Very simple, unformatted doc of cleanups is there for now.
4083 gdbcore.h: Remove obsolete variables that described a.out
4084 section addresses and offsets. (See core.c above.)
4085 Declare fetch_core_registers and registers_fetched.
4087 getopt.c: Declare char *alloca(); even on SPARC.
4089 infcmd.c (run_command): Call target_kill rather than
4091 (step_command, next_command, stepi_command, nexti_command):
4092 Declare from_tty parameter even though we don't use it.
4093 (run_stack_dummy): argument BUFFER is a char array, not
4094 a pointer to REGISTER_TYPE.
4095 (finish_command): using_struct_return needed a value *,
4096 not a struct symbol *.
4098 * infptrace.c (child_xfer_memory): To avoid dependency on
4099 where sections are in memory, try PT_WRITE_D and if that fails,
4100 try PT_WRITE_I. Most Unixes don't care which you use.
4102 * infrun.c (step_resume_break_shadow): Change to array to
4103 match other breakpoint shadow storage.
4104 (clear_proceed_status): Pass address of bpstat to
4105 bpstat_clear, not the bpstat itself.
4106 (child_create_inferior): FIXME comment about if the child
4108 (start_inferior): Remove old function.
4109 (child_open): Use target_kill rather than kill_inferior.
4110 (wait_for_inferior): Ditto.
4111 (insert_step_breakpoint, remote_step_breakpoint): Use
4112 new step_resume_break_shadow.
4114 * inftarg.c (child_wait): If all child processes die,
4115 pretend that the one being waited for exited with signal 42.
4117 * main.c (command_line_input): When scanning for comments,
4118 don't coredump on unclosed quotes.
4119 (quit_command): Use target_kill rther than kill_inferior.
4120 (_initialize_main): Rename class_user from "user" to
4123 * printcmd.c (print_command_1): Initialize "fmt" if no format
4124 is specified by the user.
4125 (print_frame_args): Only add to args_printed if we are
4126 actually fetching args from the stack (avoiding undefined
4128 (_initialize_printcmd): Remove bogus \{ from string.
4130 * remote-eb.c (eb_open): Avoid coredump on no argument.
4132 * remote-nindy.c: Bring out of Intel environment into new
4133 target environment. Remove all conditional compilation on
4134 I80960. Massive hacking throughout.
4135 (nindy_xfer_inferior_memory): New routine stolen from
4137 (nindy_create_inferior): New routine pieced together, probably
4138 not quite working yet.
4139 (nindy_ops): New target_ops struct for nindy.
4141 * remote-vx.c: Use write_memory rather than target_write_memory
4142 to get error checking.
4143 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4145 (vx_create_inferior): Use target_terminal_ours...
4147 * signame.c (_initialize_signame): Always initialize, since
4148 we need the table for things other than psignal.
4150 * solib.c (solib_add): Use symbol_file_add, not add_file.
4151 (solib_address): Return boolean result rather than struct
4152 pointer which nobody else knows the type of.
4154 * sparc-tdep.c, valops.c: Use write_memory rather than
4155 target_write_memory, to get error checking.
4157 * stack.c (locals_info, catch_info, args_info,
4158 get_selected_block, frame_command, up_command): Use
4159 target_has_stack, rather than have_inferior_p or
4162 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4164 * symfile.h: New file, defining the interface between the
4165 generic and object-file-specific symbol reading code.
4167 * symtab.c: Move generic symbol-reading interface to symtab.c,
4168 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4169 table to map BFD targets to symbol-reading modules in GDB.
4170 Change index to strchr.
4171 (lookup_struct_elt_type): Use error() rather than hand-made
4172 simulations thereof.
4173 (lookup_partial_symbol): Speedup slightly when length == 0.
4174 (symbol_file_add): New function.
4175 (symbol_file_command): Call it.
4176 (symfile_open, symfile_init): New function.
4177 (add_file_target_command, add_file_addr_command): moved from
4180 * target.c (target_command): use target_kill.
4182 * target.h (target_files_info): Don't declare, never called
4185 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4186 files to determine stack end address.
4188 * valarith.c (value_x_binop, value_x_unop): Change error message
4189 to be more useful. Pass proper argument to value_struct_elt.
4191 * valops.c (value_assign): FIXME comment that long long
4192 bitfields will break here.
4194 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4195 Update `make saber_gdb' to work better.
4197 * TODO: A woman's work is never done.
4199 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4200 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4201 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4202 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4203 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4204 valops.c, valprint.c, exec.c: Lint.
4207 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4209 Continuing Intel 960 port merge of GDB.
4211 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4212 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4213 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4214 Wack over "make depend" so it handles files in subdirectories
4215 vx-share, nindy-share, bfd, and in the current directory.
4217 * blockframe.c (get_prev_frame_info): Remove fatal error
4218 if stack not defined.
4220 * core.c (core_open, core_detach): New functions that handle
4221 the old "core-file" command as "target core" and "detach" instead.
4222 (core_file_command): Call them.
4223 (core_xfer_memory): Use common routine xfer_memory.
4225 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4226 dbxread now uses bfd for everything but symbol reading itself.
4227 BFD internals are used to drag out the relevant file offsets.
4228 (partial_symbol_file_open): Change args all around for BFD.
4230 * symtab.c: Rename "value" to "val" everywhere, so we can
4232 (symbol_file_command): New command, moved from dbxread.c
4233 and coffread.c. It uses BFD to read the file, then vectors
4234 based on its type, to dbx or coff symbol readers.
4235 * symtab.h: Extern a few vars for symbol_file_command.
4237 * target.h: Breakpoint takes a char * save area, not a char **.
4239 * valprint.c (val_print): When unpacking bitfields, offset
4240 the address in gdb of the value, if it is declared with a shorter
4241 type. Remove the last "runtime kludge test" of host byte order.
4243 * utils.c: Remove old my_bfd_read routine.
4245 * stack.c (frame_info): Use target_has_stack. Print program counter
4246 register's actual name rather than "pc", since it's called the
4247 "ip" (instruction pointer) on the i960 (sigh).
4249 * target.c (target_command): Add command for selecting a target
4250 type and calling its open routine. This is used for initiating
4251 communication with a particular target, in a generic way.
4253 * tm-i960.h: Update for modern gdb. Remove semicolons from
4254 various macros. Handle reading struct return convention, and
4255 error-out attempts to return structs with the "return" command.
4256 Be sure gdb doesn't think we know how to call functions in the
4259 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4260 to i960_xxx in lower case.
4261 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4262 not being defined yet.
4264 * remote.c (remote_open): Call start_remote to initialize
4265 wait_for_inferior during open.
4266 (remote_xfer_inferior_memory): Return length written rather
4269 * remote-vx.c (target_command -> vx_open): Use new generic
4271 * remote-eb.c, inftarg.c, exec.c: ditto.
4273 * infrun.c: Fix comments.
4274 (attach_program -> child_open): Use new generic target command.
4275 (wait_for_inferior): Clear saved register values before target_wait,
4276 so target_wait can set some of them if convenient.
4278 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4279 Return success indicator, not void.
4280 (child_xfer_memory): Avoid fetching initial word if we'll
4281 overwrite it anyway.
4283 * infcmd.c (attach_command): Use new generic target open routine.
4284 (_initialize_infcmd): Update doc on attach and detach commands.
4285 (do_registers_info): Merge in a byte-order problem as a FIXME
4288 * findvar.c (find_saved_register): Avoid problem in current frame.
4289 (read_relative_register): Ditto.
4290 (write_register): Convert byte order on the way out.
4292 * exec.c (file_command): Add.
4293 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4294 (xfer_memory): Common function between core_xfer_memory and
4296 (exec_xfer_memory): Use it.
4298 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4300 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4301 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4302 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4304 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4306 Merge Intel 960 port of gdb, continuing...
4308 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4309 symbol_file_command): Pass from_tty arg to hush 'em up.
4311 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4312 Add magic numbers for 960 COFF format.
4314 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4316 Merge Intel 960 port of gdb, from Intel "1.2" release.
4318 CHANGE_LOG entries from their port, which was based on
4321 Thu Sep 6 11:02:22 PDT 1990
4322 Remove temp file if download is interrupted.
4324 Wed Aug 1 09:08:33 PDT 1990
4325 Now uses binary protocol to talk to NINDY.
4326 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4327 Times out after 5 seconds when trying to talk to NINDY.
4329 Tue May 29 12:54:49 PDT 1990
4330 Added variable baud rate (-b switch).
4331 Source code reorganization.
4333 Thu Apr 26 11:09:55 PDT 1990
4334 More cleanup of batch mode; specifically, execute "-s", "-e", and
4335 "-se" switches as soon as they are encountered on the invocation line.
4337 Fri Apr 20 13:47:15 PDT 1990
4340 Thu Apr 19 09:54:28 PDT 1990
4341 Add 'reset' command.
4343 Wed Apr 18 09:48:07 PDT 1990
4344 After opening remote tty, wait for 1 second to go by without input
4345 from it before trying to talk to NINDY (fixes problems with the
4346 Heurikon HK80/V960E).
4348 Mon Apr 4 16:33:05 PDT 1990
4349 Some output was not being suppressed in 'batch' mode.
4351 Thu Mar 22 15:31:11 PST 1990
4352 Ask user if old symbol table should be deleted when new file is
4355 Allow user to run a program downloaded before gdb960 was brought up.
4357 Correct "exec-file" help message for i80960 context.
4359 Correct bug in calculating user space address: could occasionally
4360 corrupt user program.
4362 Make sure to zero low-order bits in rip's because of bug in 960CA
4363 A-step part: could cause operation faults when "next"ing across
4366 Correct bug that made it impossible to get source line numbers for
4367 code loaded at addresses higher than 0x7fffffff.
4369 Wed Jan 10 12:43:22 PST 1990
4370 Open remote tty for exclusive use.
4372 Fri Jan 5 12:14:42 PST 1990
4373 Correct disassembly (CA manual was right after all):
4374 opcode for sysctl is 0x659
4376 Mon Oct 23 12:03:04 PDT 1989
4377 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4379 Mon Oct 16 14:15:09 PDT 1989
4380 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4382 Mon Oct 2 15:56:31 PDT 1989
4384 Added 960CA disassembly support.
4386 To simplify maintenance:
4387 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4389 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4390 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4391 - made disassembly interface identical to that in gdmp960.
4395 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4397 * target.h: Allow targets to stack. Add target_has_memory,
4398 _registers, etc. Restructure memory access and "info files"
4399 to walk the target stack.
4400 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4401 target.c: Change tables to match target.h.
4402 * inflow.c (child_mourn_inferior): pop child_ops.
4403 (generic_mourn_inferior): Use new has_stack flag.
4404 * infptrace.c (child_xfer_memory): New memory regime.
4405 * inftarg.c (child_files_info): New "info files" regime.
4406 * remote-eb.c: New memory regime, new info files.
4407 * remote-vx.c: New memory regime, new info files. Now use
4408 separate targets for VxWorks attachment to machine, and
4409 actually running a process under VxWorks, since one has
4410 stack & execution & regs and the other doesn't.
4411 * remote.c: New memory regime, new info files.
4412 * sparc-xdep.c (fetch_core-registers): New memory regime.
4413 * target.c: New routines and support for stacked targets,
4414 new memory regime, new info files regime.
4417 Generalize section handling for an arbitrary number of sections,
4418 including use of the new BFD (binary file) library.
4419 * gdbcore.h: Add struct section_table.
4420 * exec.c (build_section_table): Iterate all sections and
4421 record what gdb needs to know about them.
4422 (exec_command): Use it.
4423 (exec_xfer_memory): Use the table.
4424 (exec_files_info): Print the table.
4425 * core.c (core_file_command, core_xfer_memory, core_files_info):
4427 * source.c (find_source_lines): Use bfd_get_mtime.
4428 * dbxread.c: Quick changes to make it compile with new BFD.
4429 * utils.c (error): Avoid using bfd_error in generic routines.
4431 * core.c (core_fetch_registers): Get from the ".regs" section of
4433 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4435 * inferior.h (attach_flag): Export.
4436 * infcmd.c (run_command): use new target_create_inferior.
4437 * infrun.c (child_create_inferior): Don't return result.
4438 * Makefile.dist (VERSION): 3.91.4.
4440 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4442 * breakpoint.c (bpstat_num): Handle breakpoints which have
4443 since been deleted, such as temporary breakpoints.
4444 infcmd.c (program_info): ditto.
4446 * core.c (core_file_command): Display the frame where the core
4451 * remote-vx.c (target_command): Merge in target command from
4452 targ-vx.c. A few other cleanups.
4454 * TODO, Projects: Lots more stuff to do...
4456 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4458 Massive changes to wall off the remote-debugging interface
4459 behind a function vector. The port to handle VxWorks targets
4460 is also part of this.
4462 All files: Replace references to renamed functions,
4463 remove references to remote_debugging, remove references to
4464 have_include_file, have_core_file in favor of target_has_stack,
4465 target_has_memory, etc.
4467 * Modularize the breakpoint interface.
4468 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4469 a breakpoint instruction.
4470 breakpoint.c: struct breakpoint's shadow_contents now sized as
4472 (insert_breakpoints): Vector to target to install breakpoints.
4473 (remove_breakpoints): Vector to target here too.
4474 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4475 sparc-tdep.c (single_step): Use new breakpoint interface for
4476 the single-step breakpoints.
4477 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4478 New file, contains routines to insert and remove breakpoints by
4479 reading out the old contents and later replacing them. This is
4480 how ptrace breakpoints work, and many remote systems as well.
4482 * tm-vxworks68.h: New config file, overrides a few things for
4483 Wind River's preferences.
4485 * target.h: New file, for transfer vector used to talk to the
4486 inferior (child, attached, core, exec, remote, etc). All accesses
4487 to the thing being debugged should come through these vectors.
4488 target.c: New file, routines to handle transfer vector.
4489 (various files): Add transfer vectors XXX_ops for the various
4490 targets and pseudo-targets (core files, etc) we support.
4492 * breakpoint.c (bpstat_stop_status): Further explorations of
4493 watchpoints and why things don't work all the time.
4494 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4496 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4497 the local gdbinit if it doesn't already have it.
4499 * core.c (core_ops): add and install.
4500 Allow core debugging without exec file.
4502 * dbxread.c (free_and_init_header_files): Merge two fns.
4503 (end_symtab): Free named symbol table when a new version comes in.
4504 (read_dbx_symtab): Relocate all kinds of symbols with base
4505 address. First step toward handling different text, data, bss
4507 (add_file_addr_command): Renamed add_file_command.
4508 (add_file_command): Vector to remote handler.
4509 Add "load" as an alias for "add-file" command.
4511 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4512 non-returning functions.
4514 * exec.c: Add exec_ops, and push it as a target when an exec
4517 * infcmd.c (run_command): Pass executable file name and arg list
4518 separately when starting an inferior. Permit "run" when no exec
4519 file is specified, for VxWorks.
4520 (detach_command): Move to child_detach in inftarg.c.
4522 * inftarg.c: New file. Unix-child-specific routines, and the
4523 child_ops structure.
4525 * inferior.h (registers): Export "registers" as the way for
4526 target dependent register handlers to find gdb's local copy of
4527 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4528 since it is now used by places that want wait_for_inferior to
4529 handle the grunge but want to see every trap from the inferior.
4531 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4532 Eliminate remote_debugging hooks in terminal handling.
4534 * infrun.c: Replace start_inferior with child_create_inferior.
4535 Move all the hair of Unix shells and ptrace idiosyncracies into
4536 child_create_inferior, so remote handlers don't have to deal.
4537 Remove running_in_shell. Rename stop_after_attach to
4538 stop_soon_quietly, and use it in a few other places where we want
4539 to just call wait_for_inferior and get control back on the first
4540 trap. trap_expected now never takes a value > 1.
4541 (init_wait_for_inferior): Initialize static vars when a new
4544 main.c (gdbinit): Add new hook for .gdbinit file name, let
4545 it be overridden by config files as GDBINIT_FILENAME.
4546 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4547 Both of these are used for VxWorks gdb.
4549 mcheck.c: rename include file "gmalloc.c" to avoid problems
4550 with system include file "malloc.c".
4552 param-no-tm.h: New include file, same as param.h but does not
4553 include the default "tm.h" file. This is used in files where
4554 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4556 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4558 remote-vx.c: New file, VxWorks remote debugging support. Uses
4559 RPC routines that are shared with the target system, in directory
4562 remote.c: Vectorize remote interface.
4564 source.c: Globalize source_path, and make an alias "l" for "list"
4565 since we now have the "load" command.
4567 sparc-xdep.c: Use new param-no-tm.h.
4569 symmisc.c (free_named_symtab): Add new function from Wind River.
4570 However, ifdef it out for now while we think about what it should
4573 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4575 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4576 non-Unix-children handle this with their own code in the target
4579 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4580 source and target lists. Add vx-share to default list of include
4581 directories. Add new files to src and target lists: mem-break,
4582 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4583 ${srcdir} versions of munch and createtags are used.
4585 * valops.c (find_function_addr): Split out of call_function.
4586 (call_function_by_hand): Rename call_function; this function
4587 calls functions in the target by laboriously patching the target
4588 word-by-word with the right stack, args, regs, etc.
4591 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4593 Handle AMD 29000 a bit better.
4595 * remote-eb.c (readchar): Mask received char log to make it readable.
4596 (remote_start): Pass arguments down to executing program.
4597 Make startaddr unsigned.
4598 infrun.c (start_inferior): Accept args, pass them to
4600 infcmd.c (run_command): Pass args down to start_inferior.
4602 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4603 the target object file format.
4604 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4606 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4607 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4609 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4611 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4612 * TODO: We did a few things, we have more to do though.
4614 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4615 * inflow.c (inferior_died): Clear deferred stores.
4617 * Debug problems with dummy frames and calls to the inferior.
4618 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4619 * sparc-tdep.c (do_restore_insn): Simplify.
4620 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4621 (sparc_push_dummy_frame): Simplify and fix what we push.
4622 (sparc_pop_frame): Slightly more hair here, deciding whether
4623 we are restoring a saved PC or returning to a return address in %i7.
4624 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4626 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4627 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4628 * obstack.h (chunkfun): ditto.
4629 * defs.h (xmalloc, xrealloc): ditto
4631 * utils.c (quit): Grab the terminal from the child if necessary.
4633 * inflow.c (term_status_command): Rename to term_info, change
4636 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4637 (is_delayed_branch): Speed up.
4638 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4639 Still missing some float ops, and needs testing.
4641 * Support for input and output radixes other than base 10
4642 * defs.h (input_radix, output_radix): Declare.
4643 * expread.y (yyparse, parse_number): Handle changes of input
4644 radix, and ambiguous names-or-numbers in radixes >10.
4645 * printcmd.c (print_scalar_formatted): Print formatted hex
4646 numbers in varying column widths.
4647 * valprint.c (val_print): Use output_format to print scalar ints.
4648 (set_input_radix, set_output_radix, set_radix): Create.
4649 (set_output_radix): Set output_format from output_radix.
4650 (_initialize_valprint): add `set radix' but leave the others off.
4652 * main.c (execute_command): Let stupid questions be turned off.
4653 (_initialize_main): Handle "set stupidity", etc.
4655 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4656 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4658 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4660 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4661 bfd stuff is still screwed up, but with some manual work, it
4664 * breakpoint.c (bpstat_do_actions): Start over if a command
4665 proceeds the inferior, since the inferior will have stopped and
4666 will need to have its new stop-actions taken care of.
4668 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4669 compiler fits, simplify it.
4671 * gdb.texinfo (directory command): Doc new dir command.
4672 source.c (directory_command): "dir" now puts things on the front
4673 of the path, moves dups up front, and handles multiple names
4674 on the command line, inserting each one in order. It also
4675 blows away cached line and full_filename info.
4677 * stack.c (backtrace_command): Skip "more stack frames follow"
4680 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4681 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4682 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4683 The only odd one was Gould NP1, which had defined vprintf to
4686 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4687 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4688 variable, inspect_it.
4689 valprint.c (print_string, val_print): Use the global inspect_it
4690 to indicate whether to print in Epoch style or normal style.
4692 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4694 * printcmd.c (call_command): add an alias for the "print" command
4695 which runs expressions and doesn't print the result if void.
4696 (print_command_1): implement it.
4698 * command.c: Remove #if 0'd code. Initialize all the fields
4699 in add_cmd (). Rename do_nothing_command to
4700 not_just_help_class_command, and make it externally visible.
4701 command.h: add user_commands to struct.
4702 * main.c (define_command): Don't overload c->function with a char
4703 string as well as a function pointer.
4705 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4706 calling convention of value_struct_elt () that got dropped in
4709 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4710 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4712 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4714 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4715 until a good time (e.g. when we are about to run the child),
4716 saving ptrace calls.
4717 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4718 * tm-sparc.h: define DO_DEFERRED_STORES.
4720 * sparc-xdep.c (store_inferior_registers): when storing float
4721 registers, don't store stack regs too. When storing the SP,
4722 however, DO store the stack regs too. This fixes a bug in which
4723 the dummy frame is not recognized when a call_function finishes,
4724 because its frame pointer (in the stack regs) was never
4726 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4727 even though we don't know how to read them from an inferior.
4728 valops.c (call_function): Comment about storing SP.
4730 * infrun.c (save_inferior_status): Save away the original bpstat
4731 chain so it can be restored later. Install the copied version for
4732 use by whoever saved the status. It will be blow away by
4733 restore_inferior_status, and the original chain restored. This is
4734 important for people who have pointers into the original.
4736 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4737 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4738 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4741 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4743 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4744 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4745 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4747 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4749 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4750 Store the baseclasses in a type struct starting from array element
4751 0 rather than from the unusual array element 1.
4753 dbxread.c: the above.
4754 (virtual_context): Add
4755 Read new debug information about which virtual function table
4756 a virtual function is from, and store it in fn_field.fcontext.
4758 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4759 TYPE_FN_FIELD_STATIC_P.
4761 symtab.c: the above.
4762 valops.c: the above. Handle pointer casts of object *'s.
4763 (search_struct_method): Add.
4764 (value_struct_elt): First arg is now a pointer to a value, and is
4767 valprint.c: the above.
4768 values.c (value_virtual_fn_field): Add type arg. Handle
4769 offsetting to the proper object when calling virtual fns.
4771 (baseclass_addr): Add valuep arg.
4773 * README: Document the current state of BFD config (missing).
4774 * TODO, ChangeLog, Makefile.dist: Roll version.
4775 * WHATS.NEW: Add summary of changes since 3.5.
4777 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4779 * dbxread.c (read_struct_type): Clear bit vectors whenever
4781 symtab.c (B_CLRALL): define.
4783 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4784 using == rather than =. Huh... This fixes the dreaded problem
4785 wherein builtin_type_int becomes TYPE_CODE_FLT.
4787 * core.c (info_files): Show the inferior pid.
4789 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4790 already knows how to look in the source directory.
4792 * Remove psymtab hair from many places. Remove duplicated code
4793 for searching symbol tables. Hide psymtabs from most places.
4794 Make it fast to get from a psymtab to its symtab.
4796 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4797 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4798 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4799 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4800 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4801 new symtab completely. New psymtabs get symtab pointer
4802 initialized to zero. Remove MI warning printf.
4803 symtab.h: Comments. Add psymtab to symtab pointer.
4804 (PSYMTAB_TO_SYMTAB): New macro.
4805 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4806 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4808 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4810 (print_frame_info): Avoid special-casing symbols that have not yet
4813 * source.c (open_source_file): Quick path if we have already
4814 located the source file by its full name.
4816 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4817 find_pc_psymtab. When a name is found in the misc function
4818 vector, search the symbol table for its mangled name, not the
4819 name that the user typed.
4821 * bfd.h: Fix missing comment terminators, make #endifs match.
4823 * valarith.c (value_less): Handle unsigned int comparisons.
4824 Add FIXME about pointer compares, which assume host and target
4825 pointers are the same.
4827 * command.c (do_nothing_command): lint
4828 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4829 fix comments on debug symbol format for visibility. Actually set
4830 visibility of symbols.
4831 main.c (echo_command): lint; use <readline/history.h>.
4832 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4833 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4834 pointing past end of allocated memory; saber complains.
4835 obstack.h: Declare the external functions that we use.
4836 valarith.h: use <string.h>
4837 solib.c (solib_add): lint.
4839 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4841 * main.c (initialize_main): Default info_verbose to off, now that
4842 symbol reading is fast.
4843 (quit_command): Avoid clobbering exec_bfd while quitting.
4845 * Initial BFD (binary file diddling library) merger:
4846 coffread.c: Change AOUTHDR to struct exe_hdr.
4848 core.c: initialize initialized data at compile time.
4849 (core_file_command): Move from coredep.c, convert to bfd.
4850 (xfer_core_file): Convert to bfd.
4851 exec.c (exec_file_command): use bfd routines.
4853 mips-tdep.c: Remove exec_file_command and friends.
4856 * coredep.c: (fetch_core_registers) Convert core_file_command to
4857 fetch_core_registers.
4858 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4860 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4861 (my_bfd_read): More bogosity, which I don't think we call.
4862 (program_name): Remove this atrocity asap!
4864 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4867 values.c: allocate_repeat_value was not clearing the
4868 optimized_out field.
4869 (value_static_field): minor stylistic fix (wrong macro was used).
4870 valops.c (value_struct_elt_for_address): didn't work for C++
4873 * signame.c (_initialize_signame): Initialize signal names once.
4875 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4876 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4877 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4879 * remote-eb.c: Support user-settable baud rates on the serial port.
4881 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4883 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4885 * tconfig/sun3os4: Remove warning about native assembler,
4886 since it also occurs in the xconfig file.
4888 * findvar.c (registers): Allocate some slop after `registers'
4889 to prevent stray accesses from trashing the next variable.
4891 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4892 on the sun-3, by changing the #ifdef from `sun3' (which is not
4893 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4894 vars, which happened to follow `registers' in the executable.
4896 * readline/history.c (history_search): Heed gcc-2's advice
4897 and parenthesize && inside ||).
4899 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4900 tm-29k.c: Insert FSF copyright headers.
4902 * remote-eb.c: Better comments.
4904 * Makefile.dist: Update to 3.91.6.
4905 * TODO: note PREPARE_TO_STORE problem.
4907 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4909 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4911 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4913 * infrun.c (wait_for_inferior, at end): Don't set up
4914 prev_* if the inferior no longer exists.
4916 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4917 CANNOT_EXECUTE_STACK.
4918 valops.c (call_function): Use it.
4920 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4922 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4923 infrun.c (wait_for_inferior, 2 places): Use it.
4925 * values.c (value_being_returned): Only use
4926 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4928 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4929 right thing for remote-eb.c.
4931 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4932 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4934 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4935 (FRAME_FIND_SAVED_REGS).
4937 * findvar.c ({fetch,store}_registers): Check for
4938 REMOTE_{FETCH_STORE}_REGISTER macro.
4940 * findvar.c (get_saved_register): Add argument lval and
4941 change meaning of argument addr.
4942 findvar.c: Change calls to get_saved_register to reflect
4943 new calling convention.
4944 valops.c (value_assign): Use get_saved_register instead of
4945 find_saved_register.
4947 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4949 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4950 an (uninitialized) pointer to one. Use "&" when passing it
4953 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4955 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4958 * coffread.c (symbol_file_command): Put semicolon after
4960 Put safe_to_init_tdesc_context in #if defined (TDESC).
4961 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4962 coffread.c: #include <sys/stat.h>.
4963 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4964 Add missing ')' in check for "lc%" and friends. Remove
4966 Declare read_one_sym() at top of file.
4967 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4968 MC68WRMAGIC can have the same value without causing a duplicate
4971 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4973 * Allow a Makefile to be built without building the
4974 tm and xm file links that screw up builds in subdirectories.
4975 This is done with `config.gdb none', then you can do things
4976 like `make gdb.tar.Z'.
4977 * tconfig/none: Config file for no target system
4978 * xconfig/none: Config file for no host system
4979 * config.gdb: If no TM or XM files are called out by the
4980 host or target file, don't make links for them.
4982 * cplus-dem.c: Add documentation.
4984 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4985 simple error, so the user's gdb doesn't crash due to some object
4986 file problem (e.g. somebody is rebuilding the file out from under
4989 * printcmd.c (print_address_symbolic): demangle the symbol.
4991 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4992 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4993 (alldeps.mak): sort and uniq all results from this; duplicates
4994 hose gdb.tar.Z link building. Remove RCS files from
4995 tconfig and xconfig. Add config files for sun386. Add
4996 a few odd files to OTHERS and HFILES.
4998 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5000 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5001 Roll version number to 3.91.5. Make lint work in bindir.
5003 * README: Document cross-debugging and new file structure.
5005 * blockframe.c: Lint. Include "value.h" to declare read_register.
5006 (find_pc_partial_function): remove duplicate line.
5008 * command.h: Lint. Declare error_no_arg and dont_repeat.
5010 * tm-news.h: Remove inadvertently duplicated stuff.
5012 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5013 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5015 * config.gdb: Allow `config.gdb host target' form. Clean
5016 up previous change that printed bogus messages when you just said
5019 * core.c: #include "command.h" for lint.
5022 * main.c: Remove some casts of enums. Lint.
5029 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5031 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5032 read it from memory. This will allow us to save ptrace calls
5033 eventually. Changed caller single_step too.
5035 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5036 that we aren't going to use, saving many ptrace calls, especially
5037 when watchpointing or single stepping. Use some #define's for
5039 (store_inferior_registers): Ditto.
5040 (core_file_command): Use some #define's for constants.
5042 * tm-sparc.h: Add #define's for some register numbers, so we
5043 can eliminate the use of random constants in sparc-xdep.c.
5045 * stack.c (frame_command, print_frame_info, up_command,
5046 down_command) Remove frame_changed, since it
5047 causes a bug and doesn't seem to do anything useful. In some
5048 places it was used as a flag, in others as a stack level (?).
5050 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5051 default is to use the portable (vprintf) version rather than the
5053 * xm-news.h (MISSING_VPRINTF): Add.
5055 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5057 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5059 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5060 about linking debugged programs -Bstatic in the sun?os4 config
5061 files in tconfig and xconfig subdirectories.
5063 * main.c (main): Remove unreached exit(0) now that we exit
5066 * Create TODO file for online bug list. There are too many
5067 "little" bugs to keep track of on paper.
5069 * Change Projects file to refer to bug-gdb@cygnus.com
5070 rather than kingdon@ai.
5072 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5074 * Makefile.dist (VERSION): 3.91.4 now.
5076 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5077 (condense_misc_bunches): Add sanity check that misc_count is
5078 the same as the number of symbols in the bunch.
5080 * coffread.c: rename init_misc_bunches. Pass an argument
5081 to condense_misc_bunches (a zero).
5083 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5084 every time we are called; don't rely on our caller to do it.
5085 (add_file): Remove call to init_misc_bunches.
5087 * mipsread.c: Only warn, don't error, if unknown symbol types.
5088 This keeps an old gdb from falling on its face if it sees newly
5089 extended symbol info. Rename init_misc_bunches.
5091 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5093 * Merge in changes from Per Bothner for DECstations and other
5094 MIPS stuff. The rest is Bothner speaking:
5096 The next message is a merger of Alessando Forin's mips port with
5097 mine. I've tried to use my good if biased judgment to get
5098 the best of both. It *does* need testing.
5100 Some of the changes are general, *not* mips-specific.
5103 Didn't believe in little-endian bit order.
5104 There are still inconsistencies about whether flags
5105 like BITS_BIG_ENDIAN are integer (#if ...) or
5106 boolean (#ifdef ...). I tried to paper over them.
5108 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5109 Moved some misc_function code that was common to
5110 {dbx,coff,mips}read.c to symtab.c.
5111 In the process, I think I cleaned things up a bit.
5112 At the same time, moved obsavestring and obconcat to symtab.c.
5115 Removed obsolete condense_addl_misc_bunches (use
5116 condense_misc_bunches(1) instead).
5119 Needed to include <sys/dir>, at least on DECstations.
5121 valops.c, mips-tdep.c, tm-mips.h:
5122 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5123 conventions (when STACK_ALIGN is insufficient).
5124 Needed on mips, where doubles need 8-byte alignment,
5125 but ints only need 4.
5128 Removed cruft that was not being used.
5129 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5132 Print $ before register-names (I think that makes things a little
5134 Never print two instructions, even if one delays.
5135 Removed hex-disassemble set_cmd. (This is not mips-specific,
5136 so I think the argument is whether it is generally worthwhile or not.
5137 I'm inclined to think not, given how easy it is to
5138 convert between radixes in gdb.)
5141 This is basically Alessando's code.
5142 It doesn't use obstacks; I changed it to use obstacks
5143 in a few minor places where using malloc causes a
5144 memory leak. (Probably, more places could/should be changed.)
5145 I added record_misc_function where it was missing.
5146 In symbol_file_command and add_file_command, I tried
5147 to make the code consistent with more recent versions.
5148 Minor sylistic changes in parse_procedure.
5149 Make a .gdbinfo. psuedo-symbol point back to the real
5150 procedure symbol (using the isym field).
5153 This is basically from my port, but with a lot of details
5154 and a number of routines merged in from Alessando's version.
5155 I basically used my code "raw" backtrace (use heuristics
5156 from the actual code, rather than symbol table info) - though
5157 the idea is Alessandro's. I feel my code is a little cleaner
5158 here, particularly in being a little more flexible, such as being
5159 able to handle gcc-produced code (which it now can).
5160 It also doesn't do frame caching (which is not useful
5161 more recent gdb versions).
5162 I also used my code for push_/pop_dummy, more or less.
5163 I tried to incorporate AF's code for testing sigtramp
5164 while backtracing; I probably got it wrong.
5165 Added mips_print_register, which tries to scrunch as much
5166 information as possible on a screen...
5167 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5168 under mips-pinsn.c), I don't see anything mips-specific here,
5169 and I don't see it being all that useful anyway.
5172 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5173 Use more register names (rather than hard-cases numbers).
5175 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5177 * Hack up 3.90.11 changes:
5179 * Makefile.dist (depend): parameterize $(GCC).
5180 Add solib.c and solib.o.
5181 (readline): Fix vpath for both absolute or relative SRCDIR.
5183 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5184 Also, let the part I didn't understand at least compile so
5185 I can test the rest. FIXME.
5187 * dbxread.c: Fix thinko using strcmp.
5188 (init_psymbol_list): declare static.
5189 (partial_symbol_file_open): Comment cleanups better, avoid
5190 cleaning up the string table since the caller will do that.
5191 Move the stat for mod time into symbol_file_command, temporarily.
5192 (There should be a mod time for each symbol file, eventually,
5193 to control its rereading. FIXME.)
5195 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5196 SunOS, which gives error for shared libs otherwise. (From
5197 Schaefer, probably FIXME needs work for portability.)
5199 * solib.c: Move #include "param.h" to work.
5200 Lowercase all the Uppercase Letters In the Messages.
5201 (find_solib): Clean up inferior_so_name for debug printouts.
5202 Allow no argument, to mean all shared libraries.
5204 * symmisc.c: include param.h to get CLEAR_SOLIB.
5206 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5208 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5209 to 3.90.11. ChangeLog entries below are from this.
5211 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5215 * Makefile.dist (HFILES): Add tm-sunos.h.
5217 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5221 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5223 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5225 * sparc-opcode.h Added single-operand version of rett.
5227 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5229 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5230 Put parens around gcc_p in expansion.
5232 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5234 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5236 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5238 * Changes for Sun shared libraries:
5239 blockframe.c (find_pc_partial_function): If a non-text symbol
5240 is found, set *address = pc - FUNCTION_START_OFFSET.
5241 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5242 Disable breakpoints instead of giving an error.
5243 source.c (select_source_symtab): Initialize cs_pst.
5244 symmisc.c: Call CLEAR_SOLIB if defined.
5245 symtab.h: Make text{low,high} CORE_ADDR not int.
5246 (psymtab): New field addr.
5248 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5249 (record_misc_function): Give correct type for N_DATA symbols.
5250 (condense_misc_bunches): do "misc_function_count = j" regardless
5252 Take code which is shared between symbol_file_command and
5253 add_file_command and put it into partial_symbol_file_{open,read}.
5254 Split add_file_command into add_file_command and add_file.
5255 Make psymtab_to_symtab read in the string table if the file
5257 Two new parameters to read_dbx_symtab and start_psymtab.
5258 tm-sunos.h: New file.
5260 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5262 * infcmd.c: Change cont_command to continue_command and "cont"
5265 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5267 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5269 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5271 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5272 size 1,2,4,8 rather than size < 8.
5274 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5275 as necessary, not just once.
5277 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5279 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5281 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5283 * tm-news.h: Add CALL_DUMMY_*.
5285 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5287 * config.gdb: In list_host, list_target, use ${i}, not $i.
5289 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5291 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5293 * sparc-opcode.h: Change all store floating-point state register
5294 instructions to have the right match & lose fields.
5296 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5298 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5300 config.gdb: If srcdir != ., create readline directory and
5301 copy a makefile into it.
5303 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5304 consistency with POSIX.
5306 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5307 when we exit its exp_valid_block.
5309 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5311 * Makefile.dist: Bump version to 3.91.3.
5313 * Clean up handling of breakpoint commands (somewhat).
5314 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5316 inferior.h: Add breakpoint_proceeded to inferior status struct
5317 and globals; save it and restore it.
5318 (clear_breakpoint_commands): Cleanup, remove old #define.
5320 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5321 (save_inferior_status, restore_inferior_status): handle it also.
5322 (proceed): Remove earlier code that set breakpoint_proceeded.
5323 It is now set only in clear_proceed_status.
5324 (clear_proceed_status): Cleanup, use bpstat_clear rather
5325 than clear_breakpoint_commands. No callers need the stop_bpstat
5326 between clear_proceed_status and proceed.
5328 infcmd.c: Add breakpoint_proceeded definition and comment.
5329 (cont_command, jump_command, signal_command): Move call to
5330 clear_proceed_status right next to call to proceed.
5332 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5333 caller's argument while running down the chain of breakpoints.
5334 Use new variable "breakpoint_proceeded" to determine when
5335 a command that it executes moves the inferior past the
5337 (bpstat_clear): Handle NULL argument.
5338 (bpstat_clear_actions): Avoid useless call to
5339 breakpoint_auto_delete.
5340 (delete_breakpoint): Clean up bpstat's that are pointing to
5341 the deleted breakpoint from the stop_bpstat chain.
5342 (breakpoint_auto_delete): Simplify.
5344 * Clean up handling of EOF, error on stdin, etc. This was
5345 prompted by a network problem that caused gdb to go into an
5346 infinite loop filling up its malloc'd memory.
5348 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5349 not clear_breakpoints_commands, which is now gone.
5350 (main): If command_loop returns (e.g. from EOF on stdin), do
5351 a quit_command (looping back to command_loop if quit_command
5352 doesn't really quit).
5353 (command_loop): check result from command_line_input and
5354 exit if it returns NULL, rather than passing the NULL to
5356 (gdb_readline): Free malloc'd result space before returning
5359 * utils.c (query): Handle C-d to mean "yes", just as if the
5360 input was not a terminal. Also avoid infinite loop if EOF
5361 occurs in mid-input-line before newline. This allows
5362 query to be used at EOF on stdin with reasonable results.
5364 * infrun.c (proceed): Set breakpoint_proceeded.
5366 * values.c (value_as_long): Avoid infinite recursion for enums.
5367 (_initialize_values): Fix typo in help msg (kingdon).
5369 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5370 RL_LIB for linking. This allows -lreadline for linking
5371 and nothing for dependencies, once readline is a real library.
5373 * config.gdb: Jim Kingdon: give useful error message if the
5374 host or target type is not recognized.
5376 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5377 it just defines it. Dumb, but deal with it.
5379 * Jim Kingdon suggests:
5380 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5382 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5384 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5386 * Clean up Bothner's changes.
5388 * blockframe.c (clear_pc_function_cache): New function.
5389 * blockframe.c: remake cache_pc_function_* static.
5390 * dbxread.c (symbol_file_command): remove references to
5391 cache_pc_function_* variables.
5392 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5393 * printcmd.c: Avoid kludging a global variable (addressprint)
5394 to avoid printing the address of a string twice. Instead,
5395 pass the format letter 's' down low enough that it can be seen
5396 to avoid this problem.
5397 (print_formatted): Pass format arg to value_print.
5398 (restore_addressprint): Remove function.
5399 (do_examine): Avoid hacking addressprint, cleanups and such.
5400 (print_frame_args): Add a comment to a Bothner change.
5401 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5402 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5403 to wipe out the values cached in blockframe.c.
5404 * symtab.c (find_method): Add comment saying how big you must
5405 allocate to be "big enough". Per being terse again.
5406 * valprint.c (val_print): Handle format letter "s" to print
5407 strings without addresses. Add comment to vtbl printing code
5408 which casts with wild abandon. Rearrange reference-printing
5410 @0xaddr: value (print w/addressprint)
5411 value (print w/~addressprint)
5412 @0xaddr (parameter lists w/addressprint)
5413 or nothing (parameter lists w/o addressprint)
5415 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5417 * Merge more changes from Per Bothner:
5419 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5420 annoying) that I tried to improve it. Here are my suggestions.
5422 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5425 Do automatic de-reference when taking the address of a reference.
5427 Don't deref_ref when printing parameter lists.
5429 More attempts at treating refernences properly.
5431 In val_print, if deref_ref==0, don't print dangling " = ".
5433 Add COERCE_REF macro, which de-references an REF.
5435 * Merge changes from Per Bothner:
5437 * Fixed (Sony news)-specific configuration problems.
5438 * Fixed other problems with using vanilla pcc and libc (enum problems;
5439 assumption that vsprintf exists).
5440 * Some major speed-ups (finc_pc_partial_function now caches a match;
5441 parsing avoids duplicate symbol_lookup calls).
5442 * Changed handling of baseclasses (no longer use baseclasses field
5443 of struct type, use the first n_baseclasses fields instead).
5444 * Various minor changes/fixes, most C++-related.
5447 Cache the most previous match from find_pc_partial_function.
5448 (Save both low and high ends of matching function's pc range.)
5449 This speeds up the loop of infrun.c:wait_for_inferior quite
5450 a bit, and makes step/next commands much zippier.
5452 Added an enum->int cast (otherwise, some compilers barf).
5454 No longer set baseclass offset to 0, since multiple
5455 inheritance now mostly works.
5456 Added a number of casts, to shut up compiler warnings
5457 (after stabs where made enums, not ints).
5458 When discarding a symbol table (in symbol_file_command),
5459 must clear the cache introduced in blockframe.c.
5460 Don't convert $vtbl_ptr_type to vtbl any more.
5461 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5462 Mask off sign bit emitted by g++ for virtual table offset.
5463 Set voffset to -1 (not 1) for static member functions.
5465 Changed parsing/lexing of names to avoid doing symbol lookup twice
5466 (once when lexing to determine symbol class, once for real).
5467 Now only call symbol_lookup once. Fields of 'this' win especially big.
5469 Subpress printing addr twice in the case of 'x/s addr'.
5471 lookup_basetype_type is no longer used.
5472 Add find_methods as recursive helper function to decode_line_1.
5473 This allows multiple inheritance to work.
5474 Also, once one or more matches has been found, do not look in
5475 base-classes. (Baseclass methods would be overridden, anyway.)
5477 Removed baseclasses array in struct type.
5478 Instead of using baseclasses[i], use fields[i-1].
5479 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5480 Changed sign convention of voffset (previous was inconsistent).
5482 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5484 Used to assume existence of vsprintf. Re-written to not need it
5485 if HAVE_VPRINTF is undefined.
5487 typecmp was too pessimistic. Made it less so.
5489 Don't print space after address.
5490 If vtable points to a misc symbol (with 0 offset), print it,
5491 since that indicates the actual class of the object.
5492 Changed ype_print_derivation_info to use new inheritance
5493 scheme (without baseclasses vector).
5495 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5496 Also, changes needed because TYPE_BASECLASSES were removed.
5498 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5500 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5503 If there is no path set, and the symbols don't indicate what directory
5504 a file was compiled in, look in the current directory. But either
5505 a path or a known compilation directory will prevent this.
5508 Three independent bug fixes:
5509 * Remove the #if 0 block that breaks some stuff.
5510 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5511 adapt gdb to either SunOS 4.0.* or 4.1.
5512 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5515 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5518 (type_print) Demangle the name being printed.
5519 (type_print_base) Handle botched demangling without coredump (tiemann).
5522 (check_stub_method): Document routine.
5523 (tiemann) fix bug for no-arg functions
5524 Avoid clobbering beyond end of malloc'd storage.
5525 Terminate the argument list properly.
5527 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5529 * Changes merged by John Gilmore:
5532 In breakpoint_1, use new print_address_symbolic instead
5533 of find_pc_partial_function. (This forces use of assembler-level
5534 addresses, and avoids misleading non-mangled source-level names.)
5536 Generalize ansi argument such that -1 means skip arglist totally.
5537 Removed global variable print_ansi_qualifiers (which made
5538 code non-reentrant), in favor of extra explicit arguments
5539 to internal routines.
5541 Add new helper function print_address_symbolic.
5542 Use find_pc_misc_function instead of find_pc_partial_function
5543 (since we want assembler-level symbols here).
5545 Print unknown function as just "f (...)", not "f (...) (...)".
5546 Use new fputs_demangled explicitly.
5548 Fixed a typing violation (problem: value.h cannot be imported
5549 without renaming many variable in this file).
5550 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5551 decode_line_1: Moved forward some never-reached code.
5552 Made decode_line_2 skip function prologues correctly.
5554 fputs_filtered should not demangle by default.
5555 Add new fputs_demangled to demangle on demand..
5557 Change value_struct_elt to use value_primitive_field (using recursive
5558 utility function search_struct_field). This allows foo.bar to work
5559 for multiple inheritance (so far only for data fields).
5560 Change check_field in the same way (recursive helper function
5561 to support multiple inheritance).
5562 (Note: there are more of these problems that I haven't fixed.
5563 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5564 value_of_this: 'this' symbol name is now just "this", note "$this".
5566 Don't print static members.
5567 Avoid printing "members of <type>" if there are none.
5568 Simplified type_print_derivation_info by merging duplicate code.
5569 Remove useless blank lines in type_print_base (ptype command).
5571 Added declaration of new routine value_primitive_field.
5573 Added value_primitive_field which is generalized version of
5574 value_field that can handle multiple inheritance (non-zero offsets etc).
5575 Re-implemented value_field to call value_primitive_field.
5577 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5579 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5580 delete the whole environment. Karl Berry reported the bug.
5581 * source.c - fix openp to avoid //'s in filenames, which
5582 trigger an Emacs bug causing it to not be able to find files
5583 when running gdb in a window.
5584 * dbxread.c - zap the #if 0 that botches the add-file code.
5585 It seems to work a lot better without all the code commented out.
5587 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5589 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5592 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5594 * Makefile - added a ${CFLAGS} to a couple of entries,
5595 added remote-sa.sparc.c
5596 * added remote.sa-sparc.c, a modification of remote.c
5597 which conducts a dialog directly with the SparcStation prom.
5598 * breakpoint.c, infrun.c, sparcdep.c added
5599 remote_insert_breakpoint(), and remote_remove_breakpoint()
5600 to breakpoint.c instead of directly writing breakpoint instructions.
5601 * sparcdep.c on remote_debugging,there is no need
5602 to remove signle step breakpoint instructions.
5603 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5605 * printcmd.c - epoch interface sends lisp expressions to open up
5606 epoch windows on inspection.
5607 * valprint.c - added arrayprint, and addressprint and made adding
5608 format controls easier
5609 * wait.h added a couple of undef's because we were getting
5610 complaints about WSTOPSIG and WTERMSIG begin redefined.

5680 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5681 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5682 when printing the type.
5684 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)

5706 step_resume_break_address != NULL, even if another_trap.
5707 If trap_expected and we enter sigtramp, then set up a
5709 If trap_expected is set when we hit the step_resume_break,
